气相色谱法测定水中溶解氩

Determination of Dissolved Argon in Water by Gas Chromatography

采用真空释放气相色谱法测定水中溶解氩。制定了新的色谱分析流程。以氢作载气，用一段催化剂柱和一段吸附分离柱，分离了氩－氧重叠峰，测得纯氩。装置简单、操作方便。测量范围为１０～２００μＬ／Ｌ，回收率约为９９．１％～１０２．６％，测定的相对误差小于±５％。

A determination technique of dissolved argon in water by gas chromatography is describedin this paper.A peak of unitary argon is acquired with a datalyst column and a column with5A molecular sieve.The range of determination is 10-200μL/ L,the recovery rate is about99.1%-102.6% and the relative error is better than±5%.
