Abstract: In the current study,2,4- Dinitrophenylhydrazine( DNPH)-silica column was used as adsorbent for preconcentration and derivatization of acetone in gas,and the derivatives were eluted with acetonitrile. The acetone derivatives were determined by a high performance liquid chromatography( HPLC) system. Various concentrations of standard gas were prepared by dynamic standard instrument with self-manufactured permeation tube of acetone. The adsorption efficiency and column capacity of the enriching column were studied under different concentration of standard gas and sampling gas flow rate.
