Tobacco or tobacco smoke condensate is extracted with aqueous acetonitrile. The filtered extract is diluted with water, and the insecticide residues are then extracted with petroleum ether. The concentrated petroleum ether extract is chromatographically purified by passage over a Florisil column and, subsequently, eluted with mixtures of diethyl ether and petroleum ether (6 and 15 % of diethyl ether, respectively). After vacuum sublimation the concentrated eluates are qualitatively and quantitatively analysed by gas chromatography using an electron capture detector and by thin-layer chromatography.
