We present a UPLC®-High Resolution Mass Spectrometric method to simultaneously screen for 19 benzodiazepines, 12 opiates, cocaine and three metabolites, and 3 “Z-drug” hypnotic sedatives in both blood and urine specimens. Sample processing consists of a high-speed, high-temperature enzymatic hydrolysis for urine samples followed by a rapid supported liquid extraction (SLE). The combination of ultrahigh-resolution chromatography with high resolution mass spectrometry allows all analytes to be uniquely detected with a 10 min analytical run. Limits of detection for all target analytes are 3 ng/mL or better, with only 300 μL of specimen used for analysis. The combination of low sample volume with fast processing and analysis makes this method a suitable replacement for immunoassay screening of the targeted drug classes, while providing far superior specificity and better limits of detection than can routinely be obtained by immunoassay.
