Identification of organic pollutants in city atmospheres

Abstract

A suitable gas chromatophic analytical technique is described for the characterization of organic components in air samples from traffic dense areas. The method employs a chromosorb 102 cold trap to collect and concetrate samples and a 30 metre SCOT DC 550 Silocone column for separating the components. Chromatograms yielding about 150 peaks have been obtained which are superior to those reported in the literature. Tentative identification could be made or paraffinic, cycloparaffinic olefinic, acetylenic and aromatic hydrocarbons in the C1 to C13 range, using a standard addition method
