氩气回路中微量水分的测量

Determination of Trace Moisture in the Argon Gas Loop

在快中子反应堆的气体回路上,用露点仪测量了快堆几个覆盖气体系统氩气中杂质水分的含量。测量时,通过将露点仪的探头从干燥器中拔出,使露点仪的本底升高1～5μL／L后再进行测量,可以较快地得到测量结果,对于测量水分含量小于15μL／L的氩气,这是方便、可行的方法。

The method determinates trace level of impurity moisture in several systems of cover gas water Argon using dewpoint meters in China experimental fast neutron reactor which is being constructed. A probe of dewpoint meters should be drawn out from a desiccator in the beginning of determining level of impurity moisture content in argon of loops on the worksite. When background of the probe increases to 1-5 μL/L, determination could be taken. Then a result could be soon made and a demand could be met in determining the trace moisture in the worksite. This is a convenient and feasible method in determining a trace level of water less than 15 μL/L.
