High-sensitivity and simultaneous analysis of Psychoactive drugs
using LC-MS/MS with full-automated pretreatment system
Introduction
LC-MS/MS has become a preferred method for the routine also increasing to investigate the cause of death. However,
analysis for forensic toxicology. LC-MS/MS allows for the manual sample preparation often involves several
simultaneous analysis of multiple compounds in a single complicated manual steps which can introduce error into
run, thus enabling a fast and high throughput analysis. In the results. In this study, we investigated the processing
recent years that it seems the number of incident and capability to analyze serum, whole blood and urine spiked
accident is increasing caused by dosed with psychotropic sixty psychotropic drugs by LC-MS/MS with automated
drugs and the number of drug testing with LC-MS/MS is sample preparation unit.
