A Procedure for Routine Use in Chromatographic Analysis of Automotive Hydrocarbon Emissions.
Environmental Sci and Technol 1971 Mar; 5(3):223-229
Procedures have been developed for routine analysis of automotive fuels and the unburned hydrocarbon of exhaust emissions. Specific attention is given to the hydrocarbon components that are photochemically reactive. Problems encountered in all phases of the analytical method are identified, and procedures that constitute a reasonable compromise between accuracy and practicality are defined. A packed and an open tubular column were used to separate the hydrocarbon content of exhaust and gasoline-vapor samples into 165 component groups; analysis time is 30 minutes. Raw chromatographic data are rapidly processed using a high-speed electronic integrator and a computer technique for automatic interpretation of chromatographic spectra.
