Testo completoNowadays, formulated petroleum products such as fuels and lubricants must respond toprecise technical requirements to ensure the best performance, reliability and longevity ofengines while limiting the emission of pollutants. This thesis work focused on the development of analytical methodologies for the identification of polymeric additives in diesel fuels and the characterization of polyalphaolefins. The additive analysis was performed by coupling of liquid chromatography, ion mobility spectrometry and mass spectrometry (LC-IMS-MS), the ionization was performed by electrospray (ESI). After adjusting the experimental parameters, all additives were identified in the diesel fuel without sample preparation. The coupling of liquid chromatography at the critical condition chromatography (LCCC) with mass spectrometry was also evaluated in order to improve the separation of additives from the diesel fuel matrix. The characterization of polyalphaolefins (PAO) was carried out by IMS-MS with ASAP (atmospheric solids analysis probe) or APPI (atmospheric pressure photoionization) sources. With ASAP, in addition to pyrolysis ions, intact species were detected for low PAO grades. In the case of high PAO grades, only pyrolytic fragments were detected, yet it was possible to identify the alphaolefins used to produce the PAOs. In APPI, the use of halogenated solvents and toluene, allowed to observe intact species for high PAO grades through the formation of halogenated adducts. With IMS-MS coupling polyalphaolefins were differentiated the by the study of drift times and full width at half maximum

Testo completoThis thesis focused on the analysis of bio-oils by supercritical fluid chromatography (SFC) in coupling with a UV detector and a high resolution mass spectrometer (HRMS). Still unknown, this technique is currently not widespread in comparison with gas chromatography. First, an optimization based on the maximization of peak capacity during the analysis of the bio-oil has been put in place. Pressure, temperature, stationary phases and mobile phases were selected to separate a maximum of peaks (more than a hundred peaks) on the widest possible retention window. Once separation optimized, an experimental work of coupling with the mass spectrometry was carried out first on a single quadrupole detector then on a time detector of flight with a linear trap (IT-ToF/MS). MS/MS fragmentation experiments were then carried out to propose an identification of the detected species. The reprocessing of the large number of data generated also necessitated the development of a reprocessing tool adapted to carry out the identification of molecular formulae and to propose developed structures using fragmentation and open-source comparison tools. The last part of this work was devoted to the comparison of the results obtained on a bio-oil by SFC-UV/HMRS, GCxGC-FI/MS and FT-ICR/MS. All of this methodological work has improved our knowledge of this type of SFC-UV / HRM coupling through application examples related to the characterization of ex-biomass complex matrices

Testo completoInnovative analytical methods have been developed to detect and quantify the organophosphorus nerve agent, VX (O-ethyl S–(2(diisopropylamino)ethyl) (methylphosphonothioate)), in plasma using liquid chromatography coupled with mass spectrometry (LC-MS/MS) technique. Liquid-liquid extraction of VX from HBSS environment was achieved with excellent yields (> 99%). Next, extraction from plasma was performed and generated a recovery rate of approximately sixty-five percent (65%). Our distinctive extraction methodology was implemented to evaluate the presence of VX in very small quantities of plasma (between 20 to 1000 µL) as in small rodents' experiments. It was followed by an LC-MS/MS analysis in a 100% organic phase. A Lux Cellulose-1 column (Phenomenex) and an Allure biphenyl column (Restek) were tested with detection limit at 0.15 pg/mL and 0.5 pg/mL in plasma (5 µL injected), respectively. Finally, our study was focused on the separation of VX enantiomers and hopeful results were provided using a Lux cellulose-2 column (Phenomenex)

Testo completoThis work is the result of a research partnership between the CEA and Les laboratories Servier. It deals with the characterization of biomarkers of metabolic enzyme induction in rat biofluids using MSbased metabolomics. The first part of this work included methodological developments regarding theacquisition and the processing of metabolic fingerprints. A tool based on autocorrelation matrices wasthen implemented to reduce the redundancy of data generated with mass spectrometry and subsequently accelerate the isolation of discriminating variables. The next step consisted in the evaluation of the combined use of Kendrick mass defects and methylene selectivity as an alternative visualization tool for large data set, which would rely on compound chemical structures. Finally, the last part of the work was dedicated to the identification of discriminating signals raised up by ametabolomic global approach from rat biofluids collected before and after an induction assay
