A rapid method was developed for the determination of diazepam, desmethyldiazepam, oxazepam, and 3-hydroxydiazepam (temazepam) in human plasma using electron capture gas chromatography. Following a single extraction with benzene from 0.2 ml plasma, diazepam and its metabolites were quantitated on

A gas-liquid chromatographic method was developed for the simultaneous assay of six local anesthetics, including amethocaine, bupivacaine, etidocaine, lignocaine, mepivacaine and prilocaine, in biological samples. These drugs and internal standard (clomipramine) in basified samples were extracted into 5 ml n-hexane

An isothermal gas chromatographic method for measuring alachlor in Micro-Tech (microencapsulated) formulations was tested by 5 collaborators. The samples were prepared in acetone, and alachlor was determined using a gas chromatographic column of 10% SP-2250 on 100-120 mesh Supelcoport. Di-n-pentylphthalate

We describe the use of electron-capture gas chromatography or reversed-phase "high-performance" liquid chromatography for concurrent analysis for diazepam and nordiazepam in serum. In the gas-chromatographic analysis our use of a new chemically deactivated stationary liquid phase, SP 2250-DB (Supelco, Inc.)
