Hydrogen/deuterium exchange reactions of protonated and sodium cationized peptide molecules have been studied in the gas phase with a MALDI / quadrupole ion trap mass spectrometer. Unit-mass selected precursor ions were allowed to react with deuterated ammonia introduced into the trap cell by a puls
## Abstract For the development of a portable gas chromatographβmass spectrometer (GCβMS) system, drastic reduction in the carrier gas load is necessary in order to minimize the pumping requirements of the mass spectrometer. Two approaches were investigated for achieving this. The first involved th
