Abstract
Determination of water and lower alcohols in household detergents was investigated by gas chromatography. Finely separated peak shape can be obtained by using porous polymer beads (Porapak-Q) as active solid, and water indicates the behavior corresponding to a case of carbon number zero in alcohol homologue. TCD is used for determination of water and lower alcohols simultaneously, and HFID is preferable for determination of only lower alcohols. Water and lower alcohols in household liquid detergents are easily identified and determined by this method.
