Quantitative Analysis of EtG and EtS in Urine Using FASt® ETG and LC-MS/MS

Ethyl glucuronide (EtG) and ethyl sulfate (EtS) are conjugated ethanol metabolites formed in low amounts in the body following alcohol consumption. This application note demonstrates cleaner extracts and lower LOD’s/LOQ’s can be achieved in the analysis of EtG and EtS using the Selectra® ETG HPLC column with UCT’s FASt® ETG SPE cartridge.
