| Abstract: | For determination of atmospheric concentrations of C4- and C5-aldehydes the method of Levaggi and Feldstein (1970) for exhaust gases was investigated and extended. The aldehydes are liberated out of their adducts in the bisulphite trapping solution. Then they are subsequently stripped out of solution by means of purified air, concentrated on a Tenax filter at 0°C and finally thermally desorbed into the gas Chromatograph for analysis. This method also appears useful for other aldehydes, which will be investigated by us. |
