Tandem ion mobility-mass spectrometry (IMS-MS) study of ion evaporation from ionic liquid-acetonitrile nanodrops.
Ion evaporation is an essential step in the formation of charged ions from electrosprays, yet many aspects of the process are poorly understood. The ion evaporation kinetics of the 1-ethyl-3-methyl-imidazolium+ (EMI+) based ionic liquids (ILs) EMI-BF4, EMI-bis(perfluoroethylsulfonyl)imide, EMI-bis(trifluoromethylsulfonyl)imide and EMI-tris(trifluoromethylsulfonyl)methide (EMI-Methide) are studi...
متن کاملDETECTION AND MEASUREMENT OF ACETONE IN THE BREATH OF DIABETICS BY ION MOBILITY SPECTROMETRY METHOD
Background: The ion mobility spectrometry (IMS) is an analytical technique that is widely used due to its high sensitivity and speed for the detection of ionized molecules in gas phase and under atmospheric pressure. Breath analysis is a new method for obtaining information about person's clinical conditions that is considered by researchers. Human exhaled air contains a variety of components s...

متن کاملLC-IMS-MS Feature Finder: detecting multidimensional liquid chromatography, ion mobility and mass spectrometry features in complex datasets
MOTIVATION The addition of ion mobility spectrometry to liquid chromatography-mass spectrometry experiments requires new, or updated, software tools to facilitate data processing. RESULTS We introduce a command line software application LC-IMS-MS Feature Finder that searches for molecular ion signatures in multidimensional liquid chromatography-ion mobility spectrometry-mass spectrometry (LC-...
متن کاملMannose7 glycan isomer characterization by IMS-MS/MS analysis.
The isomers of the Man(7)GlcNAc(2) glycan obtained from bovine ribonuclease B have been characterized by ion mobility spectrometry-tandem mass spectrometry (IMS-MS/MS). In these experiments, [Man7 + 2Na](2+) precursors having different mobilities are selected by ion mobility spectrometry and analyzed by MS/MS techniques in an ion trap. The fragmentation spectra obtained for various precursor io...
