Micromethod for determination of diazepam by electron-capture gas-liquid chromatography

E Rey et al. Clin Chem. 1977 Jul.

Abstract

We used 100 microliters of plasma for the determination of diazepam. After the internal standard, prazepam, is added, the serum is directly extracted with diethyl ether, the extract is evaporated, the residue is dissolved in ethanol, and the drug is measured by gas-liquid chromatography, with use of an electron capture detector. With this procedure, 2.5 ng of diazepam in the sample can be speedily measured with specificity, accuracy, and reproducibility (CV = 4.5%).
