A gas-liquid chromatographic method has been developed for the direct analysis of Sevin (carbaryl, 1-naphthyl N-methylcarbamate) technical grade, Sevin 85, Sevin 80, and Sevin 50 formulations. The method consists of dissolving the sample in chloroform containing Thiodan as an internal standard; an aliquot of the supernate is injected into a gas chromatograph with a flame ionization detector and a column packed with 3% SE-30 on 60-80 mesh Gas- Chrom Q. The method compares favorably in accuracy with older methods, is not subject to interferences, is rapid, and has automation possibilities.
