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

Plasma midazolam concentrations following single therapeutic doses can be quantitated using electron-capture gas-liquid chromatography. After addition of a benzodiazepine analogue as an internal standard, samples are extracted with benzeneisoamyl alcohol (98.5:1.5). The organic extract is evaporated to dryness, reconstituted, and

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.)

The gas chromatographic identification of barbiturates isolated from biological material is not optimal, and due to their polar nature, it is difficult to obtain good resolution on most columns. To improve resolution, flash alkylation appeared to be a reasonable alternative.
