title: Comparison of the possibilities of gas chromatography-mass spectrometry and tandem mass spectrometry systems for the analysis of anabolics in biological material.
abstract: Chromatographic techniques such as GC-MS play a most important role in modern multi-residue analysis of anabolic steroids. The major difference between GC-MS apparatus from different manufacturers is the way of detection and recording. Most apparatus use selected-ion monitoring (SIM) for the determination of low concentrations. Systems based on ion trap technology record in full-scan to even picogram concentrations using a computer algorithm to compare the most important peaks of the mass spectrum of the unknown to those of the standard. In this investigation the possibilities of ion trap GC-MS and the recently released GCQ MS and MS2 for the analysis of anabolics in biological material are compared.
