Abstract
A sensitive and selective method to determine diazepam, N-desmethyldia zepam, nitrazepam, flunitrazepam and medazepam in human serum and urin e was established employing solid-phase extraction and high-performanc e liquid chromatography-electrospray tandem mass spectrometry (HPLC-ES I-MS-MS) with the selected reaction monitoring (SRM) mode. Using diaze pam-d(5) and N-desmethyldiazepam-d(5) as internal standards, recoverie s between 90.4 and 109.7% were determined. The routine quantification limit was set at 2 ng/ml for serum and urine at a signal-to-noise rati o of 10:1.
