| Abstract: | Along with the development of human society and the improvement of environmental concerns, food safety becomes the hot of investigation. The analytical method of volatile organic components in food packing material has been established using Purge ＆ Trap-Gas Chromatography. Detection limit of this method was 0.01 × 10-9g/cm2 to 1.59× 10-9g/ cm2, the recovery ratios ranged were 97.3% to 99.7%, the RSD value was 0.07% to 2.77%, and the correlation coefficients of the linear coefficients were 0.9998 to 0.9999 for determined several organic solvent. Purge and trap technique has high sensitivity, low detection limit, accurate quantitative analysis and simple operation, it has shown great prospects in food and others. |
