| Abstract: | A method for the determination of organic residuals, namely, toluene, ethyl acetate, butanone and isopropanol, in plastic packing bags by headspace gas chromatography with FID by using a large _ bore capillary(d 530 m) as a chromatographic column is reported. The recovery and relative standard deviation of the method are 94.81.6% and 0.8%2.7%, respectively. The method is simple, rapid and accurate. |
