Chromatographic and spectral analytical data for the determination of benzodiazepine abuse in methadone maintenance program

Benzodiazepines are some of the most often co-abused substances in methadone treatment. Their identification in biological samples is of great importance in toxicological screening and in methadone maintenance program. The aim of this report is to describe, the analytical data making possible the identification of benzodiazepines and/or metabolites using a reversed phase liquid chromatography coupled with diode array detection.
