The aldehydes compounds were released from the automobile interior decoration materials when they were heated for 1 h in a constant temperature chamber. The aldehydes compounds were collected by DNPH (2, 4-dinitrophenylhydrazine) cartridge and then were measured by HPLC (high performance liquid chromatography). The detection limits of this method are less than 2.0 μg/m~3. Five sorts of automobile interior decoration materials were chosen for the determination of aldehydes compounds such as formaldehyde and acet aldehyde, and the results were analyzed and discussed.
