在进行水汽样品中痕量阴离子的分析时,样品在采集与分析的过程中极易受到污染。由于水汽样品中的阴离子含量一般在μg/L级范围,污染对分析结果的准确度会带来严重影响,并导致对系统运行状况的误判。本文对离子色谱分析过程中的几个污染因素,如样品采集、阴离子的时间稳定性、淋洗液以及滤膜等进行了分析,并提出了相应的控制措施。

Sample is easy to be contaminated in the collection and analysis processes when analyzing trace anion in the water and steam. Contamination can seriously influence the veracity of the result of the anal- ysis because of the μg/L level anion in the sample, and it can result in the wrong estimation of the ther- modynamic system. Some influencing factors in the ion chromatography analysis processes are studied, such as sampling, temporal stability of anion, eluent and filtering membrane. Some control strategies are put forward.
