A procedure for detecting and confirming 23 anabolic substances and/or metabolites has been developed using a GC-MS-MS ion trap system in full-scan mode. The process used to select the precursor ion,(More)
Different reversed-phase columns for basic analytes were compared for the simultaneous determination of ephedrines in urine, such as LiChrospher 60 RP-Select B, LiChrospher 100 RP18, Hypersil(More)
This paper presents an automated method for extracting anabolic agents from urine samples for their GC-MS analysis by selected-ion monitoring. The sample preparation was carried out in a(More)
