Abstract�� A new gas chromatographic method for the analysis of dicofol by a wide bore capillary column coated with Apiezon L has been studied. The major impurities of dicofol 40% benzene solution were separated. The quantitative analytical method of dicofol technical in which di n octyl phthalate was used as internal standard gives better accuracy and precision.
