气相色谱仪常识：色谱分析中载气为什么要净化？应如何净化？哪个公司的气相色谱仪比较好？推荐一下啊！南京科捷的好像不错！所谓净化，就是除去载气中的一些有机物、微量氧。
求气相色谱分析法几个常用术语的英语解释 The stationary phase is the substance which is fixed in place for the chromatography procedure.A molecular sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases and liquids.When the mobile phase is gas，it is called eluant gas.The mobile phase is the phase which moves in a definite direction.In statistics，normalization refers to the division of multiple sets of data by a common variable in order to negate that variable's effect on the data，thus allowing underlying characteristics of the data sets to be compared.Microinjector is a kind of injector which can make injection in a very small volumn.An injector，ejector，steam ejector or steam injector is a pump-like device that uses the Venturi effect of a converging-diverging nozzle to convert the pressure energy of a motive fluid to velocity energy which creates a low pressure zone that draws in and entrains a suction fluid and then recompresses the mixed fluids by converting 。
在气相色谱分析中，把什么称为载气 在气相色谱分逗余神析2113中，把承载样5261品向既定方向4102移动的气体称为载气。1653载气就内是色谱分析中的流动相，色谱容柱中的填料或涂膜成分为固定相，实现流动相功能的就是载气。载气应具有山亏一定惰性，避免在高温状态下与活跃的气态分子发生化学反应，影响检测结果。常用载气有氮气，氩气。由于氢气具有一定危险性，目毁陵前已经很少使用，但在使用FID时，特定条件下也会考虑使用氢气作为载气。
