Gas chromatographic analysis of carbonyl sulfide in high-concentration propylene gas has been achieved using Porapak, silica gel or their combination for the separation column. On the silica gel column, carbonyl sulfide cannot be separated from propane. On the Porapak column, carbonyl sulfide is eluted between C2 and C3 hydrocarbons, and is separated completely from other compounds, although propane and propylene are eluted only with overlap. By use of the Porapak-silica gel column, however, not only carbonyl sulfide is separated completely from other compounds in propylene, but also propane can be separated from propylene. The combined column can be used also for the detection of carbonyl sulfide in propylene containing water without interference.
