title: Rapid micro-method for the measurement of ethchlorvynol in blood plasma and in urine by gas-liquid chromatography.
abstract: A rapid gas-liquid chromatographic method has been developed for use in the measurement of the hypnotic drug ethchlorvynol in small (50 microliter) volumes of either blood plasma or urine. Neither solvent transfer nor evaporation steps are used in the procedure and sources of interference have proved to be minimal. The method has been applied primarily to the analysis of specimens obtained from patients who had ingested an overdose of this drug. However with slight modification, the technique may be used in the measurement of the plasma concentrations of ethchlorvynol attained during therapy.
