Abstract The energy distribution (spectrum) of pulsed photon radiation can hardly be measured using active devices, therefore, a thermoluminescence detector (TLD)-based few-channel spectrometer is used in combination with a Bayesian data analysis to help resolve this problem. The spectrometer consists of 30 TLD layers interspaced by absorbers made of plastics and metals with increasing atomic numbers and thickness. Thus, the main idea behind the device is the deeper the radiation penetrates—the higher the radiation’s energy when the radiation impinges perpendicular to the front of the spectrometer. From the doses measured in the TLD layers and from further prior available information, the photon spectrum is deduced using a Bayesian data analysis leading to absolute spectra and doses including their uncertainties and coverage intervals. This spectrometer was successfully used in two different scenarios, i.e. for the spectrometry of the radiation field two different industrial type open beam pulsed x-ray generators and secondly in three different radiation fields of a medical accelerator.

New isotope technologies in environmental physicsAs the levels of radionuclides observed at present in the environment are very low, high sensitive analytical systems are required for carrying out environmental investigations. We review recent progress which has been done in low-level counting techniques in both radiometrics and mass spectrometry sectors, with emphasis on underground laboratories, Monte Carlo (GEANT) simulation of background of HPGe detectors operating in various configurations, secondary ionisation mass spectrometry, and accelerator mass spectrometry. Applications of radiometrics and mass spectrometry techniques in radioecology and climate change studies are presented and discussed as well. The review should help readers in better orientation on recent developments in the field of low-level counting and spectrometry, and to advice on construction principles of underground laboratories, as well as on criteria how to choose low or high energy mass spectrometers for environmental investigations.

The probability estimation of oil and gas inside certain area is essential for decision making on the industrial exploitation of oil and gas bearing features. A quantitative assessment of the hydrocarbon contour mapping accuracy using ground-based spectrometric measurements, remote, geological and geophysical data requires a special validation procedure. Its purpose is to evaluate achieved accuracy and reliability as well as the conformance to specified requirements. The input data for validation of the hydrocarbon deposit contour by field spectrometry are the one points’ locations relative to the other contours detected by independent methods, such as remote, geological and geophysical. As the field spectrometry performed along spatial trace, the geometric drifts of other methods’ cross-points are estimated. The algorithm for the validation of hydrocarbon deposit contour mapping by field spectrometry, remote, geological and geophysical data is proposed in this paper. The algorithm was tested on over the Novotroitsky and East Rogintsy hydrocarbon deposits (Ukraine). Measurements along 14 spatial traces over the Novotroitsky’s deposit and 28 traces over the East Rogintsy’s one was carried out to perform validation. The average error probability was 0.28, which demonstrates an admissible reliability of hydrocarbon deposits contours’ mapping by field spectrometry data. The preliminary validation estimates engagement during the hydrocarbon deposits mapping provides the fact-based statistical consistency of the quantitative measurements received. In addition, it is possible to filter the outliers reasonable before final information product release, which will enhance the overall reliability.

Ion mobility spectrometry is a well-known technique employed for the detection and analysis of gaseous substances. In pharmaceutical applications, it is furthermore used for structural analysis of compounds, especially in combination with mass spectrometry. In this field, the comparison of calculated collision cross sections and ion mobilities of theoretic model compounds with experimental values measured with ion mobility spectrometers helps to determine the compound’s structure. For positive mode ion mobility spectrometry, the calculated mobilities using the Trajectory Method show in general a deviation of 10% or less from experimental values. In this article, it was analyzed how well the calculated values reproduce the experimental values obtained with negative mode ion mobility spectrometry including symmetric and asymmetric analyte clusters. Furthermore, the influence of four different partial charge models on the results was investigated.

Abstract Time-/temperature-resolved Py-FIMS allows for the identification of rubber components in compounds containing normal organic additives. Signals due to polymer pyrolyzates, which may be masked by processing oil in nontemperature resolved spectra, are easily obtained. Py-FI spectra from cured BR and NR differ from the corresponding uncured samples in that signals from sulfur-containing oligomers are observed. For SBR, the signals from sulfur-containing pyrolyzates were not distinguishable in the complex mixture of hydrocarbon fragments that was produced. Therefore, unambiguous distinction between cured and uncured SBR was difficult. Since Py-FI mass spectra for rubber blends appear similar to the sum of the corresponding single component spectra, secondary reactions of chain fragments from the two blend components are minimal. These results are consistent with Curie-point Py-MS studies which also showed little interaction between components in blends. Since the Py-FI mass spectrum of the styrene-butadiene block copolymer is similar to the sum of single component spectra, it is obvious that styrene-butadiene sequences are not very abundant. In contrast, mixed oligomers containing both styrene and butadiene units are found for SBR copolymers. The absence of styrene dimer and trimer, as well as high-mass oligomers of butadiene, indicates that the amount of block styrene is very low. Furthermore, the large numbers of mixed oligomers indicates a random sequence distribution. In summary, Py-FIMS is a very effective technique for direct rubber compound analysis. The sample can be examined directly, without pretreatment, and both organic additives and the rubber components can be identified in the same experiment. With programmed heating of the rubber, one can obtain separate (time-/temperature-resolved) FI mass spectra for the organic additives and the rubber pyrolyzates. The results are interesting in that much higher mass oligomers can be observed by Py-FIMS than are detected by other methods of Py-MS. For example, while the low voltage Py-EIMS typically shows no higher oligomers than trimer or tetramer for diene rubbers, Py-FIMS shows sequences containing perhaps 15–20 monomer units. This improved performance is due mainly to (a) the close proximity of the pyrolysis chamber to the field emitter (which minimizes secondary reactions) and (b) the very soft ionization provided by the FI technique. In favorable cases, Py-FIMS can be used to study long sequences in homopolymers, copolymers, and blends. As we have noted, pendent groups (e.g., mercaptobenzothiazyl) and crosslinks may be detected among the pyrolysis products. While some rubbers (e.g., polyisoprene) thermally degrade to give high abundances of oligomers, others degrade in a more random fashion (e.g., SBR) to give very complex mixtures of pyrolyzates. Polystyrene is an interesting case in which thermal degradation by retropolymerization (unzipping) is so prevalent that the monomer is by far the dominant pyrolyzate, and long oligomeric sequences are precluded. Thus, while Py-FIMS can easily be used for qualitative identification of rubber components, more detailed information may or may not be discernible in analysis of a particular rubber sample.

A combination of (atomic force microscopy)-based fishing (AFM-fishing) and mass spectrometry allows to capture protein molecules from solutions, concentrate and visualize them on an atomically flat surface of the AFM chip and identify by subsequent mass spectrometric analysis. In order to increase the AFM-fishing efficiency we have applied pulsed voltage with the rise time of the front of about 1 ns to the AFM chip. The AFM-chip was made using a conductive material, highly oriented pyrolytic graphite (HOPG). The increased efficiency of AFM-fishing has been demonstrated using detection of cytochrome b5 protein. Selection of the stimulating pulse with a rise time of 1 ns, corresponding to the GHz frequency range, by the effect of intrinsic emission from water observed in this frequency range during water injection into the cell.

Given the continuous consumer demand for products of high quality and specific origin, there is a great tendency for the application of multiple instrumental techniques for the complete characterization of foodstuffs or related natural products. Spectrometric techniques usually offer a full and rapid screenshot of products’ composition and properties by the determination of specific bio-molecules such as sugars, minerals, polyphenols, volatile compounds, amino acids, organic acids, etc. The present special issue aimed firstly to enhance the advances of the application of spectrometric techniques such as gas chromatography coupled to mass spectrometry (GC-MS), inductively coupled plasma optical emission spectrometry (ICP-OES), isotope ratio mass spectrometry (IRMS), nuclear magnetic resonance (NMR), Raman spectroscopy, or any other spectrometric technique, in the analysis of foodstuffs such as meat, milk, cheese, potatoes, vegetables, fruits/fruit juices, honey, olive oil, chocolate, and other natural products. An additional goal was to fill the gap between food composition/food properties/natural products properties and food/natural products authenticity, using supervised and non-supervised chemometrics. Of the 18 submitted articles, nine were eventually published, providing new information to the field.

In this study, hydrothermal reaction with Na2MoO4 and Zn(NO3)2as a precursor were investigated for the synthesis of β-ZnMoO4. The β-ZnMoO4were characterized by the X-ray diffractometer (XRD), electron microscopy with the field emission scanning electron microscopy with energy dispersive X-ray spectrometer (FE-SEM-EDS), high resolution X-ray photoelectron spectrometry (HR-XPS), UV-vis diffuse reflectance spectrometry (UV-DRS), and Fourier transform infrared spectrometry (FT-IR). Diffuse UV-vis spectra show the β-ZnMoO4materials to be indirect semiconductors with an optical bandgap of 2.48-2.64 eV. The photocatalytic efficiencies of powder suspensions were evaluated by measuring the Victoria Blue R (VBR) concentration. This is the first reveal that excellent activities of β-ZnMoO4are a promising visible-light-responsive photocatalyst.

Near infrared (NIR) spectrometry has found wide use in academic applications, forensic research and in industry. While the use of NIR has been extended to new fields, there have also been enormous developments in the field of multivariate calibration. Some of these developments were due to demands in NIR applications while others came from related spectral techniques. In this paper some trends and developments in multivariate calibration and the use of NIR spectrometry are presented and commented upon. A complete overview would be quite impossible, but an attempt is made to present a good selection of what is going on in the field, with appropriate comments.

Imaging spectrometry plays a significant role in various scientific realms. Although imaging spectrometers based on different schemes have been proposed, the pursuit of compact and high-performance devices is still ongoing. A compact broadband and ultrahigh-resolution imaging spectrometer (CBURIS) is presented, which comprises a microlens array, multiple fiber bundles, a microscope, and a two-dimensional detector array. The principle of the device is to spatially sample and integrate the field information via the front microlens array and then further process with the fiber bundles and imaging system based on the multimode interference theory. From both the theoretical and numerical analysis, this CBURIS design is a superior concept that not only achieves a 0.17° spatial resolution and ultrahigh spectral resolution (resolving power exceeds 2.58 × 106 at 1.55 µm) from the visible to mid-infrared region but also has the advantages of snapshot measurement, thermal stability, and a compact footprint compared with most existing imaging spectrometers.
