Quantitative analysis of designer benzodiazepines in urine by LC-MS/MS

In this poster, Phenomenex focuses on tracking designer benzodiazepine substances obtained illicitly. LC-MS/MS techniques are crucial for the proper identification and quantitation due to cross reactivity with benzodiazepine immunoassay kits. The study targets 14 compounds in urine using high-sensitivity fast LC analysis. A Kinetex™ Biphenyl LC column is used for chromatographic separation, coupled with a SCIEX® 4500 triple quad for MS/MS detection.
