| Abstract: | A method for the `determination of organic impurities in acrylonitrile hy XE 60capillary chromatography and 407 porous polymer packed column chromatography is de scribed. Optimum chromatographic conditions have been established by selecting column length. support grain size. liquid fiim thickness, column temperature, and carrier gas flowrate. The dotection limit is 0.1 mol/L. The reproducibility of analytical results is good. |
