PESTAB. New methods of chemical derivatization that convert non-volatile alkylbenzyldimethylammonium chloride homologs (widely used as fungicides, algicides and bactericides) into more volatile substances amenable to GC with enhanced detectability are described. A two-step derivatization procedure is presented which provides versatile methods for detection and separation and also facilitates the detection of quaternary ammonium compounds at the pg level by GC methods. The first step calls for the formation of trichloroethyl carbamate derivatives. The residue obtained in this step is then dissolved in chloroform, added to cyanogen bromide and allowed to produce cyanamide derivatives.
