The objective was to develop a GC-MS assay for the determination of free benzodiazepines using Supported Liquid Extraction (SLE). The SLE extraction mechanism is very efficient, delivering higher analyte recoveries and cleaner extracts than equivalent LLE methods.

This application note describes the extraction of 96 licit and illicit drugs of abuse from urine prior to UPLC-MS/MS analysis using EVOLUTE® HYDRO CX 96-well plates. EVOLUTE® HYDRO CX plates offer an efficient way to perform hydrolysis in the well of the extraction plate. This method provides high analyte recovery, reduced extraction time due to the elimination of a sample transfer step as well as the elimination of the column conditioning and equilibration steps, and a reduced risk for sample carryover or cross-contamination due to the elimination of the sample transfer step.

Benzodiazepines are psychoactive drugs used to treat various conditions including anxiety, insomnia, seizures and alcohol withdrawal. Long-term use can cause physical dependence and withdrawal upon cessation of use, due to this their application as medication has to be monitored and measured. This application note details an optimized extraction protocol for the use of ISOLUTE SLE+ supported liquid 1 mL sample volume columns to extract a range of benzodiazepines from human urine. This simplified and efficient extraction method has analyte recoveries from 90% with LOQs as low as 40 ng/mL. The application has also been performed with halogenated and non-halogenated extraction solvents in the interests of providing for green chemistry.
