Forensic applications of the determination of benzodiazepines in blood samples by microcolumn cleanup and high-performance liquid chromatography with reductive mode electrochemical detection.

Recently described microcolumn cleanup and high-performance liquid chromatography with electrochemical reductive mode detection have facilitated the determination of benzodiazepines in contaminated and degraded blood samples. Examples from an extensive application of the procedure to British forensic science casework are given here.
