Most carbamate pesticides cannot be analyzed directly by gas chromatography unless conversion to more suitable derivatives is carried out because they are thermally unstable. Liquid chromatography is a relatively new analytical tool that offers selectivity and moderate sensitivity for analysis of these heat-labile compounds. A commercial liquid chromatograph was evaluated and found useful for analysis of carbamate pesticides. Liquid chromatography retention times for 23 carbamate pesticides are given. The UV detector required 20 to 1500 ng for the pesticides studied to give a 25% fullscale recorder response.
