静态顶空进样气相色谱法测定水中CS_2的研究

Static headspace sampling determination of disulfide carbon in water by gas chromatography

采用气相色谱法静态顶空进样 ,极性柱分离 ,ECD检测器检测 ,对 CS2 的测定进行了全面的实验。实验表明 ,本方法简单、快速 ,并且具有精密度好、准确度高和检出限低的特点 ,完全能够满足快速分析水中 CS2 的要求。

A rapid and simple method is described for determination of disulfide carbon in water The procedure involves collecting sample by vigorous shaking of water and air with GC analysis of air extract using an electron capture detector,polar colume sepaiation This method is acurate and the lowest detection limit,which can satisfy the requirement for rapid analysis of CS 2 in water
