A gas chromatography/mass spectrometry (GC/MS) method is described which uses negative ion chemical ionization (NCI) and tandem mass spectrometry (MS/MS) for the determination of eight anabolic steroids in human urine. Eight anabolic steroids were derivatized by heptafluorobutyric anhydride (HFBA),

A novel chemical ionization/fast atom bombardment (CI/FAB) source was used to analyse alkenes by chemical ionization mass spectrometry (CI-MS) using copper ions as the ionizing agent. The Cu Y -CI mass spectra showed abundant pseudomolecular adduct ions [alkene-Cu] Y and characteristic fragment ions

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
