A method was proposed for the determination of 1-chloro-1, 2-dibromoethane (CDB) in the oils and emulsions by using a two-stage gas chromatography equipped with a four-way cock between the first column and the second one. The peak of CDB was apparently separated from those of the oils and emulsions on the second stage of gas chromatogram. The first column (4 mm × 2 m, stainless steel) of the apparatus stated hereinbefore contained 15 weight per cent of high vacuum silicone grease and 2 weight per cent of stearic acid as the stationary phase and the column temperature was maintained at 120°C. On the other hand, the second column (4 mm × 3 m, copper) contained 10 weight per cent of Thermol-2 as the phase on the support of Shimalite and its temperature was adjusted to 110°C. Analysis of the sample containing anisole (AN) as the internal standard was made by employing helium as the carrier gas with the flow rate of 60 ml per minute on the Shimadzu Gas Chromatograph 2A and 2B. The standard deviation and the mean recovery by the abovementioned method were 0.5 to 0.6% and 99.5 to 100.7%, respectively.
