Abstract

The arrangement of the chromatograph that is used for the determination of basic components in exhaust gases is described. An analysis for carbon monoxide, carbon dioxide, hydrogen, oxygen and total hydrocarbons takes 3 min. The error of the method was determined for individual components. The properties of the flame ionization detector when nitrogen and air are used for the introduction of the sample into the flame are compared. In order to evaluate the change in the composition of the hydrocarbons in exhaust gases depending on the functioning of the engine, the enrichment technique was used for sampling. The method for sampling is described and the results obtained with different functioning of the engine of an Š 110 automobile are shown.
