Gas chromatography-negative chemical ionization mass spectrometry (GC-NCIMS) has been applied to the analysis of 0-and S-glucuronides. The glucuronides were derivatized with pentafluorobenzyl (PFB) bromide and Tri-Sil, and analyzed by GC-NCIMS. All glucuronides gave a large [M-PFBI-ion indicative of
In order to utilize the selectivity of negative chemical ionization mass spectrometry for amine analysis we have examined a number of biogenic amine derivatives for detection limits, molecularly specific characterization and ease of preparation using negative chemical ionization mass spectrometry wi
The hydrogen and isobutane chemical ionization mass spectra of a number of carotenoids, with symmetrical and unsymmetrical end groups, have been examined. Similar spectra were obtained with each gas. Loss of fragments, characteristic of both the polyene chain and of the end groups were shown by all
