Abstract
Two high-throughput high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) methods were developed for the screening of five important classes of drugs in sports, namely 23 corticosteroids, 12 anabolic agents, 23 diuretics, 49 stimulants and narcotics. Sample preparation included liquid-liquid extraction, evaporation of organic layer in nitrogen stream and reconstitution of dry residue. Thereafter two HPLC-MS/MS injections from the same vial (aliquot) were done with different mode of registration: negative ions for corticosteroids and most diuretics, and positive ions for some diuretics, anabolic steroids, narcotics and stimulants.
