包装材料同食品类似,在样品检测的过程中会受到多种因素的影响,其中样品前处理条件是整个分析测试环节中的关键因素。通过具体的案例,以模拟物样品中的双酚A类物质为前处理研究目标,对金属三片罐的有害物迁移检测方法进行了详细阐述,完成了体积分数为10%和50%的乙醇及质量分数为3%的乙酸模拟物三大类产品的样品前处理方法研究。

Packaging material is similar to food and is affected by a variety of factors in the process of specimen detection. Pre-treatment of samples plays a key role in all these analysis procedures. By taking the bisphenol A substances in the food simulates as the research objectives, the detection method of harmful substance migration in 3-piece can was carefully studied. The sample pre-treatments of all of these three kinds of simulates, including 10% and 50% ethanol in volume fraction, and 3% acetic acid in mass fraction were explored
