Two-step silylation procedure for the unified analysis of 190 doping control substances in human urine samples by GC-MS.


BACKGROUND While a number of different derivatization procedures for screening GC-MS analysis of prohibited substances are followed by doping control laboratories, a unified derivatization procedure for the GC-MS analysis of 190 different doping agents was developed. RESULTS Following preliminary experiments, a two-step derivatization procedure was… (More)
