Abstract:
Laser-induced breakdown spectroscopy (LIBS), known also as laser-induced plasma spectroscopy (LIPS), is a well-known spectrochemical elemental analysis technique. The field of LIBS has been rapidly matured as a consequence of growing interest in real-time analysis across a broad spectrum of applied sciences and recent development of commercial LIBS analytical systems. In this brief review, we introduce the contributions of the research groups in the African continent in the field of the fundamentals and applications of LIBS. As it will be shown, the fast development of LIBS in Africa during the last decade was mainly due to the broad environmental, industrial, archaeological, and biomedical applications of this technique.

Abstract:
The high price of beef and its processed products has led to many cases of adulteration with pork, resulting in issues related to halal food assurance. Therefore, it is crucial to conduct identification and analysis of the types of meat used in order to maintain food halalness. One of the methods currently advancing in the identification and analysis of meat types is Laser-Induced Breakdown Spectroscopy (LIBS). The aim of this study is to determine the capability of Laser-Induced Breakdown Spectroscopy (LIBS) in identifying and analyzing various types of meat. The study results indicate that the Laser-Induced Breakdown Spectroscopy (LIBS) method is capable of identifying and analyzing meat types with simple sample preparation and accurate outcomes compared to other methods such as Real Time-PCR, Enzyme-Linked Immunosorbent Assay (ELISA), Electronic Nose System, Fourier-transform infrared spectroscopy (FTIR), and Raman spectroscopy. The Laser-Induced Breakdown Spectroscopy (LIBS) method can be combined with various chemometric methods such as PCA, PLS, and MSC. Laser-Induced Breakdown Spectroscopy (LIBS) can identify and analyze various types of meat with an accuracy of up to 100% in shrimp and clams mixed sample. In conclusion, the combination of LIBS and chemometric methods demonstrates promising results in identifying and analyzing meat types.

Abstract:
Laser-induced breakdown spectroscopy (LIBS) is emerging as an analytical tool for investigating geological materials. The unique abilities of this technique proven its potential in the area of geology. Detection of light elements, portability for in-field analysis, spot detection, and no sample preparation are some features that make this technique appropriate for the study of geological materials. The application of the LIBS technique has been tremendously developed in recent years. In this report, results obtained from previous and most recent studies regarding the investigation of geological materials LIBS technique are reviewed. Firstly, we introduce investigations that report the advancement in LIBS instrumentation, its applications, especially in the area of gemology and the extraterrestrial/planetary exploration have been reviewed. Investigation of gemstones by LIBS technique is not widely reviewed in the past as compared to LIBS application in planetary exploration or other geological applications. It is anticipated that for the classification of gemstones samples, huge data set is appropriate and to analyze this data set, multivariate/chemometric methods will be useful. Recent advancement of LIBS instrumentation for the study of meteorites, depth penetration in Martian rocks and its regolith proved the feasibility of LIBS used as robotic vehicles in the Martian environment. Keywords: LIBS, gemstone, geological samples, extra-terrestrial.

Abstract:
The laser-induced breakdown spectroscopy (LIBS) technique is one of the most promising laser-based analytical techniques. Coincidentally, the LIBS acronym was proposed by Radziemski and Loree in two seminal papers published in 1981, almost at the same time in which the Laser and Particle Beams journal started its publication. In this contribution, the evolution of the LIBS technique is discussed following a chronological collection of key papers in LIBS, some of which were in fact published on LPB.

Abstract:
Laser-induced breakdown spectroscopy (LIBS) is a technique that provides an accurate in situ quantitative chemical analysis and, thanks to the developments in new spectral processing algorithms in the last decade, has achieved a promising performance as a quantitative chemical analyzer at the atomic level. These possibilities along with the fact that little or no sample preparation is necessary have expanded the application fields of LIBS. In this paper, we review the state of the art of this technique, its fundamentals, algorithms for quantitative analysis or sample classification, future challenges, and new application fields where LIBS can solve real problems.

Abstract:
The feasibility of using laser-induced breakdown spectroscopy (LIBS) for the compositional analysis of ilmenite slag was explored. The slag was obtained from a pilot-scale ilmenite smelting furnace. The composition of major oxides TiO2, FeO, and MgO are determined by the calibrated LIBS method. LIBS measurements are done under normal atmosphere and temperature. A Q-switched Nd:YAG laser operating at 355 nm was used to create a plasma on an ilmenite slag sample. The characteristic lines based on the NIST database of Fe, Mg, and Ti can be identified on the normalized LIBS spectra for the slag samples. The spectral range chosen for the study is 370 to 390 nm. Calibration curves were plotted using the data collected from various industrial ilmenite samples of varying compositions of TiO2, FeO, and MgO. The univariate simple linear regression technique was used to do the analysis and the prediction accuracy was checked by the root mean square error (RMSE). To validate the application of LIBS, both qualitative and quantitative analysis is done and compared to the analytical ICP-OES results. The model predicts the magnesium content with the highest accuracy and gives good prediction for iron and titanium content. This study demonstrates the capability of using LIBS for the surface analysis of the ilmenite slag sample.

Abstract:
Laser-induced breakdown spectroscopy (LIBS) is a powerful technique for quantitative diagnostics of gases. The spatial resolution of LIBS, however, is limited by the volume of plasma. Here femtosecond-nanosecond dual-pulsed LIBS was demonstrated. Using this method, the breakdown threshold was reduced by 80%, and decay of continuous radiation was shortened. In addition, the volume of the plasma was shrunk by 85% and hence, the spatial resolution of LIBS was significantly improved.

Abstract:
ChemCam est à bord de la mission Mars Science Laboratory (MSL) qui a décollé pour Mars le 26 novembre 2011. Cet instrument est très innovant car c'est la première fois que la technique du LIBS ("Laser-Induced Breakdown Spectroscopy") est utilisée pour l'exploration planétaire, afin d'étudier la géochimie des sols et roches à la surface de la planète rouge. Cette technique permet de déterminer la composition chimique de la cible analysée, en focalisant un laser à sa surface. Un plasma se créé alors par échauffement de la matière. L'analyse spectrale de la lumière émise du plasma permet d'identifier les éléments présents dans la roche, ainsi que leur concentration. Ce travail de thèse contribue à la préparation du retour scientifique de la mission MSL et de l'instrument ChemCam autour de quatre axes principaux : (i) identification et caractérisation des raies spectrales pertinentes, (ii) test des méthodes de classification des roches avec ces mesures, (iii) étude de la sensibilité aux vernis d'altération des roches ou à la couche de poussière, (iv) analyse des données pour extraire des informations sur la structure et la composition des roches. Une station sol a été développée afin de reproduire les conditions atmosphériques à la surface de Mars. Une bibliothèque de raies élémentaires a été réalisée. Cette dernière est spécifique à ChemCam et à la géochimie de Mars, et contient plus de 1300 raies. Les outils de classification des roches avec les données de ChemCam se sont montrés efficaces. ChemCam permet de réaliser des analyses quantitatives, que ce soit par des méthodes statistiques ou plus conventionnelles. Nous avons montré que cet instrument est capable d'analyser aussi-bien la couche d'altération d'un basalte que la roche saine au dessous. Il permet également d'effectuer des analyses très fines, comme la comparaison de différentes matrices de roches volcaniques, ou encore de la structure interne des argiles. Pour finir, ces études expérimentales réalisées durant la thèse ont démontré que ChemCam répondait à toutes les spécifications imposées au début de sa conception
ChemCham is onboard the Mars Science Laboratory (MSL) mission, which was launched the 26th November 2011. This instrument uses the LIBS (Laser-Induced Breakdown Spectroscopy) technique to study the geochemistry of the Martian surface. This technique is used for the first time for the Space and Planetary exploration. In LIBS technique a pulsed laser beam is focused on a target, creating a plasma. The spectral analysis of the plasma light is collected to observe the characteristic emission lines of the elements present in the sample. This work contributes to the preparation of the scientific returns of the MSL mission but also of ChemCam, with four principal axes: - identification and characterization of the significant elemental lines, - test of the method used to distinguish rocks with these measurements, study of the capacity to analyze the alteration coating on rocks, - data analysis to extract informations about the structure and/or composition of rocks A ground station was developed in order to be representative of the Martian surface conditions. An elemental lines database specific of ChemCam and Mars is performed, with up to 1300 lines. Several experimental studies let us to characterize some of the ChemCam capabilities. First, rocks classification is successful whatever the kind of the sample. Some parameters were studied to understand their influence on the classifications. Then, quantitative analysis with ChemCam are feasible, not only using statistical methods. We show that ChemCam is able to analyze the composition of the alteration coating before the one from the unaltered rock, deeper. It is also able to make some differences between several kinds of basalts with their texture and matrix, and between several kinds of clays, looking at their internal structure

Abstract:
Tato doktorská práce je zaměřena na vývoj algoritmu ke zpracování dat naměřených zařízením pro spektrometrii laserem indukovaného plazmatu (angl. LIBS). Zařízení LIBS s tímto algoritmem by mělo být následně schopno provést třídění vzorků a kvantitativní analýzu analytu in-situ a v reálném čase. Celá experimentální část této práce byla provedena ve Spolkovém institutu pro materiálový výzku a testování (něm. BAM) v Berlíně, SRN, kde byl sestaven elementární LIBS systém. Souběžně s experimentílní prací byl vytvořen přehled literárních zdrojů s cílem podat ucelený pohled na problematiku chemometrických metod používaných k analýze LIBS měření. Použití chemometrických metod pro analýzu dat získaných pomocí LIBS měření je obecně doporučováno především tehdy, jsou-li analyzovány vzorky s komplexní matricí. Vývoj algoritmu byl zaměřen na kvantitativní analýzu a třídění vyvřelých hornin na základě měření pomocí LIBS aparatury. Sada vzorků naměřených použitím metody LIBS sestávala z certifikovaných referenčních materiálů a vzorků hornin shromážděných přímo na nalezištích mědi v Íránu. Vzorky z Íránu byly následně na místě roztříděny zkušeným geologem a množství mědi v daných vzorcích bylo změřeno na Univerzitě v Clausthalu, SRN. Výsledné kalibrační křivky byly silně nelineární, přestože byly sestaveny i z měření referenčních vzorků. Kalibrační křivku bylo možné rozložit na několik dílčích tak, že závislost intenzity měděné čáry na množství mědi se nacházela v jiném trendu pro jednotlivé druhy hornin. Rozdělení kalibrační křivky je zpravidla přisuzováno tzv. matričnímu jevu, který silně ovlivňuje měření metodou LIBS. Jinými slovy, pokud určujeme množství analytu ve vzorcích s různou matricí, je výsledná kalibrační křivka sestavená pouze z jedné proměnné (intenzity zvolené spektrální čáry analytu) nepřesná. Navíc, normalizace takto vytvořených kalibračních křivek k intenzitě spektrální čáry matrčního prvku nevedla k výraznému zlepšení linearity. Je obecně nemožné vybrat spektrální čáru jednoho matričního prvku pokud jsou analyzovány prvky s komplexním složením matric. Chemometrické metody, jmenovitě regrese hlavních komponent (angl. PCR) a regrese metodou nejmenších čtverců (angl. PLSR), byly použity v multivariační kvantitatvní analýze, tj. za použití více proměnných/spektrálních čar analytu a matričních prvků. Je potřeba brát v potaz, že PCR a PLSR mohou vyvážit matriční jev pouze do určité míry. Dále byly vzorky úspěšně roztříděny pomocí analýzy hlavních komponent (angl. PCA) a Kohonenových map na základě složení matričních prvků (v anglické literatuře se objevuje termín ‚spectral fingerprint‘) Na základě teorie a experimentálních měření byl navržen algoritmus pro spolehlivé třídění a kvantifikaci neznámých vzorků. Tato studie by měla přispět ke zpracování dat naměřených in-situ přístrojem pro dálkovou LIBS analýzu. Tento přístroj je v současnosti vyvíjen v Brně na Vysokém učení technickém. Toto zařízení bude nenahraditelné při kvantifikaci a klasifikaci vzorků pouze tehdy, pokud bude použito zároveň s chemometrickými metodami a knihovnami dat. Pro tyto účely byla již naměřena a testována část knihoven dat v zaměření na aplikaci metody LIBS do těžebního průmyslu.

Abstract:
The analysis of white latex paint is a problem for forensic laboratories because of difficulty in differentiation between samples. Current methods provide limited information that is not suitable for discrimination. Elemental analysis of white latex paints has resulted in 99% discriminating power when using LA-ICP-MS; however, mass spectrometers can be prohibitively expensive and require a skilled operator. A quick, inexpensive, effective method is needed for the differentiation of white latex paints. In this study, LIBS is used to analyze 24 white latex paint samples. LIBS is fast, easy to operate, and has a low cost. Results show that 98.1% of variation can be accounted for via principle component analysis, while Tukey pairwise comparisons differentiated 95.6% with potassium as the elemental ratio, showing that the discrimination capabilities of LIBS are comparable to those of LA-ICP-MS. Due to the many advantages of LIBS, this instrument should be considered a necessity for forensic laboratories.

Abstract:
Aluminum alloy castings are becoming commonplace for critical applications in the automotive and aerospace industries where materials failure is not an option. In order to meet such property demands, tight control over the cleanliness of the melt (mitigation of solid particle inclusions) and microstructure must be achieved. In order to control cleanliness, it must first be well defined and measured. Very few techniques exist in industry that can quantitatively measure inclusion levels in-situ. Laser-induced breakdown spectroscopy (LIBS) is presented as a promising technique to quantify solid particles, desired or undesired, in aluminum melts. By performing LIBS with subsequent statistical analysis on liquid aluminum with varying concentrations of Al2O3, AlB2, TiB2, and SiC particles, calibration curves relating particle concentration and elemental intensity were drawn. Through metallography and automated electron microscopy, it was found that inclusions less than 10 um in size could be detected with LIBS. Concentrations down to at least one part-per-million could be detected and accurately measured, allowing for LIBS to be use as a tool for complete, real-time melt cognition.

Abstract:
Elemental analysis in forensic laboratories can be tedious and many trace evidence items are not analyzed to determine their elemental composition. Presently, scanning electron microscopy-energy dispersive x-ray spectroscopy (SEM-EDS) is the primary analytical tool for determining the elemental composition of trace evidence items. However, due to the time it takes to obtain the required vacuum and the limited number of samples that can be analyzed at any one time, SEM-EDS can be impractical for a high volume of evidence items. An alternative instrument that can be used for this type of analysis is laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). While LA-ICP-MS is a very precise and quantitative analytical method that determines elemental composition based on isotopic mass measurements; however, the instrumentation is relatively expensive and therefore is budgetarily prohibitive for many forensic laboratories. It is the purpose of this research to evaluate an inexpensive instrument that can potentially provide rapid elemental analysis for many forensic laboratories. Laser induced breakdown spectroscopy (LIBS) is an analytical method that meets these requirements and offers information about the elemental composition based on ionic, atomic and diatomic molecular emissions.

Abstract:
A capacidade do instrumento Laser Induced Breakdown Spectroscopy (LIBS) foi investigada para a possibilidade de atuar como uma ferramenta de quantificação. Um instrumento de baixo custo fechado do dispositivo de acoplamento de cargas (CCD) foi utilizado a fim de quantificar (K), (Ca), (Mn), (Mg), e (Cu) presente em 26 amostras de fertilizantes constituídos de diferentes matrizes, alguns fosfato de organo-mineral e outros de material inorgânico (quantificação de elementos presentes em fertilizante organominerais nunca tinha acontecido). Duas técnicas de referências foram utilizadas para validar as habilidades de quantificação: Plasma Acoplado Indutivo-Espectroscopia de Emissão Ótica (ICP-OES) e Espectroscopia de Absorção Atômica (AAS). O melhor pico representando cada elemento foi encontrado para produzir a melhor correlação entre cada pixel CCD e a concentração de elementos obtidos a partir das técnicas de referência. O pico mais adequado de LIBS foi tratado com um procedimento de normalização, a fim de corrigir os efeitos de matriz e as pequenas flutuações no plasma. Após o pico produzido por LIBS ser normalizado, foi linearmente montado contra os dados das duas técnicas de referência e duas curvas de calibração para cada um dos elementos foram construídas. Quando o procedimento de normalização não foi aplicado, valores de R-quadrado diminuiu entre 0,1-0,2 em quase todos os elementos. No entanto, entre os resultados produzidos pelas duas curvas de calibração, após o procedimento de normalização ser aplicado, os valores de correlação R-quadrado variaram de 0,8-0,98, o que foi considerado adequado para os elementos de interesse. O LOD para LIBS também foi calculado e verificou-se que quando os valores estavam abaixo do limite de determinação, a validade de LIBS como uma ferramenta de quantificação diminuiu. Além disso, uma análise de erro de validação cruzada foi feita com LIBS-ICP e LIBS-AAS, o que originou valores de erro de 22% - 28% para alguns dos elementos, quando todas as amostras foram incluídas. Mas quando as amostras abaixo do LOD foram excluídas, aqueles valores de erro desceram significativamente, e resultou na gama de 7% - 20%. Uma análise de validação cruzada também foi feita para as concentrações dos elementos determinados pelas técnicas de referência e esses resultados produziram valores de erro variando de 9% - 23%. As semelhanças entre os valores de erro LIBS e os valores de erro das técnicas de referência, dá credibilidade para a capacidade de LIBS para atuar como uma ferramenta para a quantificação de elementos presentes em fertilizantes compostos de diferentes matrizes.
The ability of the instrument Laser Induced Breakdown Spectroscopy (LIBS) was investigated for the possibility of acting as a quantification tool of analysis. A low-cost gated charged coupled device (CCD) was used in order to quantify (K), (Ca), (Mn), (Mg), and (Cu) present in 26 fertilizer samples made up of different matrixes, some of organic-mineral phosphate and others of inorganic material; evaluation of elements in organomineral fertilizers had never been done by LIBS. Two reference techniques were used in order to validate the quantification abilities: Inductive Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) and Atomic Absorption Spectroscopy (AAS). The best peak representing each element was found by finding the best correlation between each CCD pixel and the element concentration obtained from the reference techniques. The most appropriate peak from LIBS was treated with a normalization procedure in order to correct for physical matrix effects and small plasma fluctuations. After the LIBS peak was normalized, it was linearly fitted against the data from the two reference techniques, thus two calibration curves for each element were built. When the normalization procedure was not applied, R-squared values decreased between 0.1 - 0.2 in almost all the elements. However, amongst the results of the two calibration curves after the normalization procedure was applied, R-squared correlation values ranged from 0.8-0.98, which were considered adequate for the elements of interest. The LOD for LIBS was also calculated and it was found that when values were below the LOD, the validity of LIBS as a quantification tool decreased. Moreover, a cross-validation error analysis was done with LIBS-ICP and LIBS-AAS, which yielded error values of 22% - 28% for some of the elements when all samples were included, but when samples below the LOD were excluded, those error values went down significantly, and resulted within the range of 7% - 20%. A cross-validation analysis was also done for the element concentrations determined by the reference techniques and those results yielded error values ranging from 9%- 23%. The similarities between the LIBS error values and the reference techniques error values, gives credibility to the ability of LIBS to act as a tool for quantifying elements in fertilizers composed of different matrixes.

These performances present a high interest for military applications to detectchemical agent traces on surfaces. The aim of this study is to investigate the potential of thistechnology in the detection of specific chemical atoms of live agents such as phosphorus,fluorine, chlorine, and sulfur on the surface of contaminated samples representing thetheatre. In order to improve the analytical performances of classical technical LIBS of singlepulse, a double pulse method was developed and compared to single pulse method. Itsprinciple is based on the emission of two successive laser impulsions resolved in space andtime, generating in the focal point thermal plasma which relaxes in fine emitting specificradiation of the elementary composition. The analytical gains, as for detection thresholdsare evaluated for each type of samples. A comparison of the detection thresholds isestablished

Abstract:
As a consequence of the widespread use of computers coupled to high-quality printers and different types of papers, forgery, counterfeiting, change of wills, anonymous letter writing and felonious use of the documents have become serious problems. Forensic analysts are always seeking methods that can provide reliable information on whether a specimen collected at the crime scene is linked to the crime or to a source of known origin. Sensitive methods that can provide more detailed characterization of natural or man-made materials or even provide information not previously available to forensic examiners. Recent advances in rapid solid sampling of materials using laser ablation (LA) coupled to inductively coupled plasma mass spectroscopy (ICP-MS) have led to this analytical method to be regarded as the “gold standard” in the field of elemental analysis for trace level components in solids. Another, emerging, analytical technique that uses the same laser pulse to generate a plasma that can be interrogated with spectroscopy is laser induced break down spectroscopy (LIBS). The analysis of ink and paper is also possible because of the surface removal effect of laser interactions with the samples. In the present study, printing inks were analyzed using LIBS, LA-ICP-MS and both of them in tandem mode. In the tandem setup, the light generated during the relaxation of the excited species (LIBS) was used to create a spectral signature of the elements, and the mass-to-charge ratio of the ejected particles (ICP-MS) was used to create a mass spectrum. For a set of 319 printing ink samples, LA-ICP-MS alone provided discrimination greater than 99%. A subset of 43 printing inks, having a very similar elemental profile, was analyzed by tandem LIBS/LA-ICP-MS. The fusion of LIBS and LA-ICP-MS provided additional discrimination through the detection of elements like Ca, Si, Fe, and K by LIBS, that are difficult to detect and confirm using standalone ICP-MS because of the spectral interferences (isobaric and polyatomic) involved. The combination of these two sensors was found to minimize the individual limitations and provide a more complete and representative chemical characterization of printing inks.

Abstract:
The Army is interested in sensors capable of characterizing/monitoring the environment (battlefield or military training ranges) at proximal distances. Recently, we evaluated laser induced breakdown spectroscopy (LIBS) systems (hand-held, proximal, and bench top) for the characterization of metals (antimony, copper, lead, tungsten, and zinc) in soils obtained from military training ranges. We then compared the results to findings obtained with standard field and laboratory instrumentation for metals analysis -X-ray Fluorescence (XRF) and Inductively Couple Plasma- Optical Emission Spectroscopy (ICP-OES).

Abstract:
Laser-induced breakdown spectroscopy (LIBS) is a rapid, low-cost analytical method with potential applications for quantitative analysis of soils for heavy metal contaminants found in military ranges. The Department of Defense (DoD), Army, and Department of Homeland Security (DHS) have mission requirements to acquire the ability to detect and identify chemicals of concern in the field. The quantitative potential of a commercial off-the-shelf (COTS) hand-held LIBS device and a classic laboratory bench-top LIBS system was examined by measuring heavy metals (antimony, tungsten, iron, lead, and zinc) in soils from six military ranges. To ensure the accuracy of the quantified results, we also examined the soil samples using other hand-held and bench-top analytical methods, to include Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) and X-Ray Fluorescence (XRF). The effects of soil heterogeneity on quantitative analysis were reviewed with hand-held and bench-top systems and compared multivariate and univariate calibration algorithms for heavy metal quantification. In addition, the influence of cold temperatures on signal intensity and resulting concentration were examined to further assess the viability of this technology in cold environments. Overall, the results indicate that additional work should be performed to enhance the ability of LIBS as a reliable quantitative analytical tool.

Abstract:
Handheld laser-induced breakdown spectroscopy (LIBS) is an emerging analytical technique that shows the potential to replace X-ray fluorescence spectroscopy (XRFS) in the field characterization of soils containing heavy metals. This study explored the accuracy and precision of handheld LIBS for analyzing soils containing copper and zinc to support LIBS as a re-placement for XRFS technology in situ. Success was defined by handheld LIBS results that could be replicated across field analyzers and verified by inductively coupled plasma–optical emission spectrometry (ICP-OES). A total of 108 soil samples from eight military installations were pressed into 13 mm pellets and then analyzed by XRFS and LIBS. Handheld LIBS has a spot-size area 100-fold smaller than that of XRFS, and though it provided accurate measurements for NIST-certified reference materials, it was not able to measure unknown soils of varying soil texture with high particle size variability, regardless of sample size. Thus, soil sample particle size heterogeneity hindered the ability to provide accurate results and replicate quantitation results across LIBS and XRFS. Increasing the number of particles encountered by each shot through particle size reduction improved both field-analyzer correlation and the correlation between handheld LIBS and ICP-OES from weak (<15%) to strong (>80%).

Abstract:
Commercially available handheld chemical analyzers for forensic applications have been available for over a decade. Portable systems from multiple vendors can perform X-ray fluorescence (XRF) spectroscopy, Raman spectroscopy, Fourier transform infrared(FTIR) spectroscopy, and recently laser-induced breakdown spectroscopy (LIBS). Together, we have been exploring the development and potential applications of a multisensor system consisting of XRF, Raman, and LIBS for environmental characterization with a focus on soils from military ranges. Handheld sensors offer the potential to substantially increase sample throughput through the elimination of transport of samples back to the laboratory and labor-intensive sample preparation procedures. Further, these technologies have the capability for extremely rapid analysis, on the order of tens of seconds or less. We have compared and evaluated results from the analysis of several hundred soil samples using conventional laboratory bench top inductively coupled plasma atomic emission spectroscopy (ICP-AES) for metals evaluation and high-performance liquid chromatography (HPLC) and Raman spectroscopy for detection and characterization of energetic materials against handheld XRF, LIBS, and Raman analyzers. The soil samples contained antimony, copper, lead, tungsten, and zinc as well as energetic compounds such as 2,4,6-trinitrotoluene(TNT), hexahydro-1,3,5-triazine (RDX), nitroglycerine (NG), and dinitrotoluene isomers (DNT). Precision, accuracy, and sensitivity of the handheld field sensor technologies were compared against conventional laboratory instrumentation to determine their suitability for field characterization leading to decisional outcomes.
