Quantitative Analysis of 21 Benzodiazepine Drugs, Zolpidem and Zopiclone in Serum using UPLC/MS/MS
17 May 2012The objective of this note is to develop a UPLC/MS/MS method for the quantitation of 21 benzodiazepines, Zolpidem and Zopiclone in human serum. A quantitative method based on liquid/liquid extraction (LLE) and UPLC with tandem mass spectrometry (MS/MS) is described. The methods performance was been evaluated using authentic samples.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.
