A partition chromatographic method for determining the gamma isomer content of benzene hexachloride products is described. The partition solvents are nitromethane and n-hexane and the supporting medium is silicic acid. The method is sufficiently convenient and rapid for routine production analysis, and requires no expensive equipment or specially trained personnel. The accuracy is about 2% based upon the actual gamma isomer content of synthetic mixtures of the isomers. The procedure appears to be adaptable to the determination of some of the other isomers and related constituents. © 1948, American Chemical Society. All rights reserved.
