This application note describes the extraction of 25 illicit and prescribed drugs from hydrolyzed urine using ISOLUTE® HYDRO DME+ Dual Mode Extraction plates prior to UPLC-MS/MS analysis.
Because of the enhanced sample clean up delivered by ISOLUTE HYDRO DME+ products, analyte sensitivity is significantly increased compared to traditional dilute and shoot (D&S) techniques, resulting in reduced limits of quantitation (LOQ)
