摘要

Platinum impregnated metal oxide semiconductor gas sensing elements, one with tungsten oxide and the other with tin oxide, were successfully applied as the detection element for high-resolution gas chromatography when moisturized oxygen was used as reagent gas. Among the semiconductors, the tin oxide semiconductor had greater selectivity, more sensitivity to fatty acids and less sensitivity to hydrocarbons. In contrast, the tungsten oxide semiconductor had more universal sensitivity to the compounds tested.
