title: A rapid screening procedure for acidic and neutral drugs in blood by high resolution gas chromatography.
abstract: A rapid high resolution gas chromatographic method for screening acidic and neutral drugs in blood is described. The procedure involves a single extraction with ethyl acetate. Using flame ionization detection, without derivatization and with on-column methylation, more than 60 drugs of toxicologic importance are detected.
