Forensic Screening for Drugs in Urine Using High-Resolution MS/MS Spectra and Simplified High-Performance Screening Software
Instrument Type: LCMSMSForensic toxicologists need an economical solution to screen for a virtually unlimited number of compounds in urine. Here we present a method for screening using a dilute-and-shoot approach with the Q Exactive Focus mass spectrometer and Thermo Scientific ToxFinder software. For forensic use only.
Quantitation of 122 Drugs in Urine by Triple Quadrupole Mass Spectrometry
Instrument Type: LCMSMSForensic toxicologists face an ever-expanding list of compounds for analysis. This note presents work done using a next-generation triple quadrupole mass spectrometer with fast SRM acquisition speed for quantitation of 122 analytes in a single chromatographic run, where scan speed does not impact sensitivity or quantitative performance. Compounds analyzed include opiates, opioids, benzodiazepines, barbiturates, amphetamines, tricyclic antidepressants, illicit compounds, and more. For forensic use only.
