摘要
在动态顶空进样-气相色谱分析中,参数设置不合理会导致一些沸点较高的有机挥发物在测试系统中有残留,对结果有很大影响。本文通过改变升温参数,使残留现象得到明显改善,从而能准确测定样品中高沸点有机挥发物的含量。
High boiling point compounds residue will be remained in the automated thermal desober system when performing dynamic headspace outgassing test,the problem is resolved after developing the method,and the confirmed datum was acceptable.
