title: Analysis of chlormethiazole, ethchlorvynol and trichloroethanol in biological fluids by gas-liquid chromatography as an aid to the diagnosis of acute poisoning.
abstract: A simple method has been developed whereby chlormethiazole, ethchlorvynol and trichloroethanol can be simultaneously detected and measured in biological fluids. The procedure is based upon the rapid extraction of a small (50-microliter) sample volume with an equal volume of chloroform containing an internal standard, followed by the gas-liquid chromatographic analysis of this extract. Specimens of blood plasma or serum, urine and gastric contents can be used, and no interference from either endogenous or exogenous sources has been observed. The method is suitable for the measurement of the plasma concentrations of these compounds attained after overdosage.
