Endosulfan ANALYSIS
Product analysis by i.r. spectrometry (CIPAC Handbook, 1970, 1, 360) or by glc (ibid., 1985, 1C, 2110; AOAC Methods, 1995, 983.08). Residues determined by glc with MCD (ibid., 976.23; Pestic. Anal. Man., 1979, 201-A, 201-G, 201-I; 405; A. Ambrus et al., J. Assoc. Off. Anal. Chem., 1981, 64, 773; Man. Pestic. Residue Anal., 1987, I, 5, 6, S19; Anal. Methods Residues Pestic., 1988, Part I, M1, M12). In drinking water by gc with ECD (AOAC Methods, 1995, 990.06). Further methods available on request from Aventis.
