title: Gas--liquid chromatographic determination of free dimethindene in human serum and urine at low concentrations.
abstract: A simple method for the determination of dimethindene down to a concentration of 10 ng/ml in human urine and serum is described. After the addition of an internal standard, the dimethindene is extracted as the free base with pentane. Measurements are made directly by gas--liquid chromatography using a flame ionization detector.
