The elution curves in gel filtration using two kinds of bio-bead gel (S-X 2 and S-X 8) were measured for tristearin, fatty acid, cholesterol and its ester which were considered to be the main components of organic soils from the practical application of underwear.<BR>When chloroform was applied as the elution solvent, only one peak was observed in the both elution curves in gel filtration of the mixed lipid using S-X 2 and S-X 8. On the other hand, many peaks corresponding to the components contained in lipid mixture were observed in elution curve obtained by the gel filtration using S-X 2 gel and benzene as the elution solvent. The relations between the elution volumes corresponding to peaks in elution curves and molecular weight were discussed.
