Gas-solid Chromatographic Analysis of Automobile Tailpipe Emissions as a Function of Different Engine and Exhaust System Modifications
A single, relatively short gas-solid porous-layer open-tubular Chromatographic column was used to separate aliphatic hydrocarbons, aromatic hydrocarbons and some inorganic gases (O2, CO and CO2) found in automobile exhaust. The column's performance and longevity did not appear to be affected by the presence of water or carbon dioxide in the samples. The concentrations of the emission gases varied considerably with changes in air/fuel ratio, coil voltage and use of catalytic converters. The results of the analyses were compared with those obtained using a commercial emission analyser (“sniffer”).
