運(yùn)動(dòng)員尿液中藥物殘留的固相萃取和lc-ms分析

a routine drug screen was implemented tocomplement existing methods of analysistargeting thermally labile and other difficult todetect compounds that are not adequatelycovered by other screens.samples were analysed on a triple quadrupoleliquid chromatograph-mass spectrometer (lcms)by se-lected reaction monitoring (srm) inboth positive and negative atmospheric pressurechemical ionization (apci) modes.introductiona large emphasis has been placed on drugtesting laboratories to increase efficienciesthrough generating faster analytical run times.liquid-chromatography mass spectrometry (lcms)with an apci interface is today a powerfulanalytical tool. lc-ms/ms or lc-msn allows forbroader ranges of drugs to be analysed withgreater se-lectivity and specificity in complexmatrices.
