两台多参数水质仪在线监测比对结果分析及方法评估

本文对两台多参数水质仪在线监测结果与标准方法进行了比对分析及方法评估。结果表明，两台仪器的水温、盐度、DO、pH、浊度等检测结果与标准方法具有较好的相关性。由于比对方法的原理、干扰因素、采样方式等的不同，部分因子比对的结果存在一定差异。但多参数水质仪在线监测优势在于高频率连续监测，采用多参数水质仪开展业务化在线监测工作是可行的，是传统监测方式的必要补充。

The comparative result analysis and method evaluation of two multiple parameters of water quality on-line monitoring

The article which illustrates the comparative analysis and the method evaluation between the results of standard methods and the two online multi-parameter water quality analyzers.The results show that the parameters such as temperature, salinity, dissolved oxygen, pH and turbidity of the two water quality analyzers have good relativity to the results from standard methods.There are some diversity results from specially appointed factors due to the difference between principles of methods, interference factors, methods of sample collection and so on.Online multi-parameter water quality analyzers can be used for operational works because the ability of high frequency continuously monitoring, it is an essential supplementary to traditional methods.
