Comparison between triple quadrupole, time of flight and hybrid quadrupole time of flight analysers coupled to liquid chromatography for the detection of anabolic steroids in doping control analysis
Pozo, Óscar J.; Van Eenoo, Peter; Deventer, Koen; Elbardissy, Hisham; Grimalt Brea, Susana; Sancho, Juan V; Hernandez, Felix; Ventura, Rosa; Delbeke, Frans T. Elsevier (2011-01-17)Triple quadrupole (QqQ), time of flight (TOF) and quadrupole-time of flight (QTOF) analysers have been compared for the detection of anabolic steroids in human urine. Ten anabolic steroids were selected as model compounds ... -
Detection and Characterization of a New Metabolite of 17α-Methyltestosterone
Pozo, Óscar J.; Van Eenoo, Peter; Deventer, Koen; Lootens, Leens; Van Thuyne, Wim; Parr, Maria K.; Schänzer, Wilhelm; Sancho, Juan V; Hernandez, Felix; Meuleman, Philip; Leroux-Roels, Geert; Delbeke, Frans T. The American Society for Pharmacology and Experimental Therapeutics (2009-11)The misuse of the anabolic steroid methyltestosterone is currently routinely monitored in doping control laboratories by gas chromatography-mass spectrometry (GC-MS) of two of its metabolites: 17α-methyl-5β-androstane-3α,17β-diol ... -
Detection and characterization of anabolic steroids in doping analysis by LC-MS
Pozo, Óscar J.; Van Eenoo, Peter; Deventer, Koen; Delbeke, Frans T. Elsevier (2008)The detection of target anabolic steroids in doping analysis has generally been performed by gas chromatography combined with mass spectrometry (GC-MS). However, liquid chromatography combined with tandem mass spectrometry ... -
Detection and structural investigation of metabolites of stanozolol in human urine by liquid chromatography tandem mass spectrometry
Pozo, Óscar J.; Van Eenoo, Peter; Deventer, Koen; Lootens, Leens; Grimalt Brea, Susana; Sancho, Juan V; Hernandez, Felix; Meuleman, Philip; Leroux-Roels, Geert; Delbeke, Frans T. Elsevier (2009)The applicability of LC-MS/MS in precursor ion scan mode for the detection of urinary stanozolol metabolites has been studied. The product ion at m/z 81 has been selected as specific for stanozolol metabolites without a ... -
Direct quantification of steroid glucuronides in human urine by liquid chromatography-electrospray tandem mass spectrometry
Pozo, Óscar J.; Van Eenoo, Peter; Van Thuyne, Wim; Deventer, Koen; Delbeke, Frans T. Elsevier (2008)A method based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the direct quantification of glucuronides of testosterone (TG), epitestosterone (EPG), androsterone (AG) and etiocholanolone (ETG) has been ...
