GC7990 超纯气体中微量水测定气相色谱仪

Ultra pure gas preparation and the use of ultra pure gas in gas protection, many industrial department is often need analysis for trace water in the gas. At present most commonly used is the dew point method, the downside is instrument can only be dedicated; With GC7990 high thermal conductivity detector sensitivity gas chromatograph, it not only can easily detect trace water in ultra pure gas, but also can be used to measure trace gases impurity in the ultra pure gas and other organic material analysis. Gas chromatograph is simple, and it's convenient accurate quantitative.

                超纯气体制备和用超纯气体做保护气的许多工业部门,对气体中微量水是需要经常分析的。目前常用的大都是露点法,其缺点是仪器只能专用;而用GC7990高灵敏度热导检测器气相色谱仪,不但可方便地测出超纯气体中的微量水,而且还可以测定超纯气体中的微量气体杂质及作其它有机物分析之用。气相色谱仪操作简单,定量也较方便准确。
