The objective of the work was to investigate the application of a catalytic combustion ionization detector to the determination of hydrocarbons in automotive exhaust. The catalytic element is a coiled platinum hot wire of the general type used in conventional catalytic combustion detector cells in which thermal effects are measured. In the present device the effect measured is the ion current resulting from charged radicals formed during the process of catalytic combustion. A major feature of this technique for auto exhaust gas analysis is its complete selectivity to C2+ hydrocarbons in the presence of CO, H2, CH4, CO2, air and H2O. The study examined the effect of operating parameters on selectivity to different types of hydrocarbons, results were compared to those obtained with the Flame Ionization Detector, and typical results on actual auto exhaust samples are reported.
