Abstract
In the study, 41 participating laboratories were instructed to analyze two solutions of ethyl acetate containing different mixtures of lindane, heptachlor epoxide, DDE, and dieldrin both before and after dilution with canned evaporated milk supplied with the sample. This was done to compare various techniques and ascess their accuracy. Gas chromatography with a microcoulometric titration was used by one participant, and the electron capture detector was used by 38 participants; thin-layer and paper chromatography were each used by one participant. Most participants achieved separation of pesticides either by use of a florisil clean-up column or a gas chromatograph column containing a mixture of a polar and a non-polar liquid phase, or by use of both techniques.
