采用气相色谱法测定复合食品包装膜、袋中二氨基甲苯及其不确定度评估
Determination and Uncertainty Assessment of 2,4-diaminotoluene in Composite Laminated Food Packaging Films and Bags with Gas Chromatography
摘要
Abstract
The study was to evaluate the uncertainty of 2,4-diaminotoluene in composite laminated food packaging films and bags with gas chromatography and provide the market safety analysis of the products.The 2,4-diaminotoluene content in composite laminated food packaging films and bags was determined with gas chromatography.The uncertainty components in testing process were analyzed and calculated through math-ematic model.Finally,the relative synthesis standard uncertainty and the relative expansion uncertainty were calculated out.Result was that linear relationship,reproducibility and stability of the method with gas chroma-tography were good.The linear correlation coefficient was 0.99910.The detection limit was 0.0006mg/L. The average recovery was 9 1 .7%.The evaluation results showed that the extended uncertainty of measurement results was 0.164X(k=2).The errors of the fitting of the standard curve and the recovery of the sample were confirmed as the major sources of the uncertainty in determining 2,4-diaminotoluene in composite laminated food packaging films and bags with gas chromatography.关键词
