Direct Analysis in Real Time (DART™) high-resolution Orbitrap™ mass spectrometry (HRMS) combination with Raman microscopy was used for the detailed molecular level characterization of explosives including not only charge but also complex matrix binders, plasticizers, polymers, and other possible organic additives. A total 15 defused military weapons grenades, mines, rockets, submunitions, mortars were examined. Swabs wipes to collect trace (residual) amounts their constituents from...
Laser desorption ionization Fourier transform ion cyclotron resonance mass spectrometry (LDI-FTICRMS) was used to investigate particulate matter (PM) associated with mainstream (MSS) and sidestream cigarette smokes (SSS). The high resolution the measurement accuracy allowed a molecular formula for each detected signal in 150-500 m/z range be assigned. number of peaks observed spectra required additional data processing extract information. In this context, Kendrick maps Van Krevelen diagrams...
Detailed molecular composition of solid phase extracted dissolved organic matter (SPEDOM) collected from fractured-rock groundwater was compared to connected surface river water at two different watersheds in the unconfined chalk aquifer Champagne France using full scan ultrahigh resolution electrospray and photoionization Fourier transform ion cyclotron mass spectrometry (FT-ICR MS), Orbitrap tandem MS (MS/MS) 1H magnetic resonance spectroscopy (NMR). NMR indicated that SPEDOM carried a...
The objective of this study was to describe an analytical validation a simple, rapid, sensitive, and selective liquid chromatography (LC)-tandem mass spectrometry (MS-MS) method for quantification metronidazole in human plasma samples from bioavailability studies. were pre-treated by liquid.liquid extraction (LLE) with ethyl acetate. Metronidazole the internal standard (IS) zidovudine analyzed combined reversedphase LC-MS-MS positive ion electrospray ionization. Multiple reactions monitoring...
The chemical composition of the particulate phase cigarette smoke inhaled by active smoker is still poorly known in spite its importance from a health point view. A non-targeted approach applied to particles collected on quartz filter obtain an as complete possible description this complex mixture.
Metronidazole is a BCS (Biopharmaceutics Classification System) class 1 drug, traditionally considered the choice drug in infections treatment caused by protozoa and anaerobic microorganisms. This study aimed to evaluate bioequivalence between 2 different marketed 250 mg metronidazole immediate release tablets. A randomized, open-label, 2×2 crossover was performed healthy Brazilian volunteers under fasting conditions with 7-day washout period. The formulations were administered as single...
Aerosols from the mainstream cigarette smoke have been analyzed by electrospray ionization (ESI) coupled to Fourier transform ion cyclotron resonance mass spectrometry (FTICRMS). Measurements conducted in positive mode. The chemical composition of aerosol is significant because it gives insights one complex indoor environmental mixture. Almost 1300 compositions relative nitrogen species were successfully determined through accurate measurement and good production used technique. most...
Nowadays, synthetic polymers are produced and used in many materials for different applications. Matrix-assisted laser desorption/ionization or electrospray mass spectrometry classically to investigate them, but these techniques require sample preparation steps, which not always suitable the study of insoluble formulated polymers. Alternatively, direct real-time (DART) ionization analysis may be conducted without preparation. Four polyvinylidene fluoride (PVDF) involving C2H2F2 repeating...
This chapter reviews the use of direct analysis in real time-mass spectrometry (DART-MS) context screening (qualitative) and quantitative pollutants environmental contaminants. The contaminants mentioned are mainly derived from chemical industries, agricultural practices, or human personal care products (PCPs), ultimately released into compartments such as surface/underground waters, soils, atmosphere. Pesticides cover a large number substances with varying groups, all sharing common...
The concentrations of twelve dioxin-like polychlorobiphenyls (DL-PCB) were determined in fifty-seven soils by gas chromatography coupled to tandem mass spectrometry (GC-MS/MS). investigated collected a 72 km2 area close Algiers, the Algerian capital. highest cumulated DL-PCB concentration was 82 µg kg−1. use principal component analysis (PCA) ensured tentative identification contamination sources, which found be associated with release into environment PCB commercial mixtures from electrical...
Secondary organic aerosols (SOAs) represent a significant portion of total atmospheric aerosols. They are generated by the oxidation volatile compounds (VOCs), and particularly biogenic VOCs (BVOCs). The analysis such samples is usually performed targeted methods that often require time-consuming preparation steps can induce loss and/or sample contaminations.Recently, untargeted using high-resolution mass spectrometry (HRMS) have been successfully employed for broad characterization...
The iodine transfer polymerization of vinylidene fluoride (or 1,1-difluoroethylene, VDF) controlled by 1-iodoperfluoroalkanes or 1,8-diiodoperfluoroctane led to oligo(VDF)s containing one two end-atom(s). Their deep characterizations utilizing size exclusion chromatography (SEC GPC), 1H and 19F NMR FT-IR spectroscopies, matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF) revealed low dispersities, indicating a pseudoliving nature the reaction. In...
