热裂解-气相色谱质谱联用法快速检测聚丙烯材料中5种抗氧剂

Application of PY-GC/MS in Rapid Determination for 5 Kinds of Antioxidants Polypropylene

采用热裂解气质联用仪,建立了一种无需任何样品前处理、全程无溶剂的、同时对5种常用塑料抗氧剂的定量分析方法。结果表明:通过该方法分析的5种常用抗氧剂,在0.2~1μg之间有很好的线性关系,且该方法操作简单、快速准确,填补了热裂解气质联用技术在塑料助剂定量分析的空白。

A method for quantitative analysis of 5 kinds of common plastic antioxidants without any sample pretreatment,solvent-free in the whole process and without any sample pretreatment was established.The result show that the linear relationship between 0.2~1μg for the 5 commonly used antioxidants analyzed by this method is very good.The method is simple,rapid and accurate,and fills in the blank of quantitative analysis of plastic additives by pyrolysis gas chromatography-mass spectrometry.
