Enhanced Detection and Separation of Anabolic Steroids for Anti-Doping Control Screening by Comprehensive Two- Dimensional Gas Chromatography Time-of-Flight Mass Spectrometry (GCxGC-TOFMS)

This experimental method employs GCxGC to increase peak capacity and resolution in combination with time-of-flight mass spectrometry (TOFMS) detection followed by data processing with deconvolution software algorithms for positive confirmation of anabolic steroids in urine.
