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),

We report an isotope dilution mass spectrometry method using capillary gas chromatography negative ion chemical ionization for the determination of cortisol in human plasma. Cortisol was derivatized with pentafluoropropionic anhydride at room temperature and measured by selected ion monitoring of th
Doping control studies for the detection of clenbuterol in human urine was studied. Confirmation was achieved by trifluoroacetylation after cyclic fluorophenylboronation to produce FPBA-clenbuterol, for derivatization over 10 min at 80 ยฐC, measured using negative chemical ionization (NICl) and NICl-
Because of its high sensitivity, gas chromatography negative ion chemical ionization mass spectrometry (GC-NCI-MS) is a potentially valuable analytical tool for the stndy of cholesterol metabolism. Of several derivatives prepared for potential use in tracer studies pentafluorobenzoyl cholesterol was
We describe a method for quantifying diacylglycerols as their 1-pentafluorobenzoyl-2-acyl-3-acetyl-glycerol derivatives by capillary gas chromatography-negative ion chemical ionization-mass spectrometry. The basis of the method resides in the sequential treatment of diacylglycerols with acetic anhyd
