[Gas-liquid chromatography with Fourier-transform infrared spectrophotometry. Application in the analysis of drugs. 2: Benzodiazepines].

High working temperatures were used during the separation of benzodiazepines by capillary gas chromatography with Fourier transform infrared detection (FTIR). Spectral identification of these drugs give very good results with 10 micrograms of drug injected. On the contrary, the precision of the quantitative determination is poor.
