INTRODUCTION Numerous methods for the analysis of animal and poultry products for chlorinated insecticide residues have appeared in the literature. Most methods lack sensitivity, are specific for one insecticide, or require excessive time for analysis. A semi-quantitative method described by Mills (1959) is sufficiently sensitive and could be used to detect several insecticides, but it requires considerable sample preparation prior to actual analysis. Later, Watts and Klein (1962) reported on the use of electron capture gas chromatography (ECGC) for the detection of nanogram quantities of certain chlorinated insecticide residues. These authors used the Mills (1959) procedure for clean up of samples to prevent detector contamination. There is a need for a rapid clean up procedure for fatty animal product samples. Langlois et al. (1963) reported on a one step florisil column procedure for clean up of dairy products prior to ECGC analysis of selected chlorinated insecticide residues. Since the method… |
