Abstract
A chromatographic procedure for the separation of smoke condensate or smoke condensate fractions into groups of unpolar or little polar, polar, and heavily polar components is described and is shown to offer a possibility of estimating the mode of action of fractionation mechanisms as well as of comparing different fractionation processes. Experiments carried out on defined substances were found to give some information about the adherence of individual classes of compounds to the said groups. The chromatographically obtained fractions were characterized through their infra-red spectra.
