| 摘 要： | 为了提高挥发性有机物(VOCs)分析的准确性,笔者考察了3种采样罐和2种气袋对116种VOCs的保存效果。结果表明:VOCs在不同种类采样罐和气袋中的保存情况有一定差异,整体上Silonite采样罐的保存效果相对更稳定,罐内水分含量会对部分VOCs的保存效果造成影响(特别是对含氧有机物);保存实际样品时,能保证VOCs分析准确性的时间为12 d。

| Abstract: | In order to ensure the accuracy of volatile organic compounds (VOCs) analysis,this study investigated the preservation effects of three kinds of sampling cans and two kinds of air bags on 116 kinds of VOCs.The results showed that the preservation conditions of VOCs in different kinds of sampling cans and air bags varied to a certain extent.On the whole,the storage effects of Silonite® sampling cans were relatively stable.The moisture content in the cans might affect the storage effects of some VOCs,especially oxygen-containing organic matters.When the actual samples were stored,the time to ensure the accuracy of VOCs analysis was 12 days. |
