Development of reference material for hexachlorobenzene and three isomers of hexachlorocyclohexane in ginseng root sample to assure the quality control of organochlorine analysis was presented. The assigned values of the reference material were determined using an accurate isotope dilution gas chromatography-mass spectrometry technique.
