✦ Synopsis

A method for the determination of ultratrace amounts of lindanc by ccntripetal thin-layer chromatography combined with gas chromatography under common laboratory conditions is described. The method was used for the determination of pesticide contents in the dry material obtained from cabbage from a trial field. The accuracy of the analysis under the conditions easily available in routine work is 0.1 p,p,b. The sensitivity limit of the method is 0.00~ p.p.b, with analytical precision.
