| 摘 要： | 利用大体积进样技术结合气相色谱-质谱仪器，对二噁英的测定效果进行了研究．对进样量1，5，10，25，50μL和100μL的色谱图进行了分析，同时与传统分流／不分流进样技术进行了对比．对比和研究表明：使用大体积进样方式完全可以代替传统分流／不分流进样技术，并且不影响色谱分离度，又可以大幅度提高仪器分析的灵敏度．

| Abstract: | Performance for dioxin determination by gas chromatography-mass spectrometry coupled with large volume injection was studied.The chromatograms of the injection volume of 1,5,10,25,50 and 100 μL was analyzed.The comparison between large volume injection and traditional split/splitless injection showed that the separation performance was not affected and analytical sensitivity is greatly increased. |
