A gas chromatography/mass spectrometry method is described which uses negative ion chemical ionization and tandem mass spectrometry for the determination of anabolic steroid metabolites. Four anabolic steroid metabolites to be derivatized by Pentafluoropropionic anhydride (PFPA) were determined usin
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-
