| Abstract: | A method for analysis of residual toluene in plastic packing bags by gas chromatographic headspace analysis is presented. This method is very simple and accurate. It only requires one column: 0.5 m x 2 mm i.d. packed with 102 white support DMCS coated with 20% PEG-20M. The relation between the preheating temperature of sample and the peak height of toluene can be approximately expressed as H=4.156e(0.126T). The precision of this method is 4% and its detectable limit is 0.031 mg (toluene)/m2. |
