To achieve rapid determination of dicarboxylic acids and hydroxy fatty acids as their underivatized forms, GC conditions including column packing material were examined. As the result, an OV-17 liquid phase coated on Tenax GC was found to give well defined, sharp and symmetrical peaks for dicarboxylic and hydroxy fatty acids. This column gave good separation for lactic, glutaric, adipic, pimeric, suberic, azelaic, sebacic and undecanedioic acids. The relative standard deviations (n=5) for the determination of dicarboxylic and hydroxy fatty acids (lactic acid, hydroxy myristic acid, hydroxy palmitic acid, hydroxy stearic acid) were less than 5.0%. As an exception, maleic and succinic acids were determined as their anhydrides after dehydrogenation by phosphoric acid retained on silica wool in the injection port.
