应用X2 ICP-MS同时分析GB5749-2006中规定的生活饮用水中的31个金属元素

生活饮用水安全关系到民众的日常起居,因此越来越多的法规对饮用水分析提出了更高的要求,本文针对生活饮用水国标GB5749-2006中的无机分析指标进行了总结,同时介绍了赛默飞世尔X Series2 ICP-MS在生活饮用水分析中的具体实验方法。ICP-MS作为目前应用广泛的痕量元素分析仪器,已经广泛适用于各类水质分析,其中,生活应用水的分析是重点应用之一。作者通过细致的仪器调整,对不同仪器操作模式样品测定结果以及模式间切换做了大量的研究,以满足日常应用的需求,此外还对仪器的一些重要的性能改进对仪器实用性的提升做了相应的评价。

Simultaneous Analysis of 31 Metals in Drinking Water Regulated in GB5749-2006 by X Series 2 ICP-MS

Drinking water safety is related about everyday life of people,so more and more regulation provides higher requirements about drinking water analysis,the article concluded the inorganic targets in drinking water national standard GB5749-2006,furthermore,introduced the detailed experimental methods applied with X Series 2 ICP-MS from ThermoFisher Scientific.ICP-MS,as one of broadly used instruments for trace elements analysis,has been applied to all kinds of water samples,among which drinking water analysis is one of the key application area.The author tuned the instrument carefully and make plenty of research about the results in different operation modes and the switch of various modes,which is fit for the routine analysis requirements.Besides the author has proposed some assessments about the instrument performance improvements to promote the practicality.
