The Quantitative Determination of Insecticides in Tobacco and Tobacco Smoke. 2^nd Report: The Determination of Carbamate Residues - Methoden zur quantitativen Bestimmung von Insektiziden in Tabak und Tabakrauch. II. Mitteilung: Zur Bestimmung von Carbamat-Insektiziden

A thin-layer chromatographic method has been developed for the qualitative and quantitative determination of carbamate residues on tobacco. The method's inferior limit of detection is 80 ng for Carbaryl and 200 ng for Undene. The coefficient of variation of the results is 5.3 % for Carbaryl and 7.7 % for Undene.
