ICP-MS相关联用技术在食品元素形态分析中的应用及进展

电感耦合等离子体质谱（ICP-MS）技术凭借其低检出限、多元素同时分析等优点，广泛应用于食品中的元素分析。随着分析技术的发展，以及元素的不同形态在物理、化学、营养、毒理等方面的显著差异，元素形态分析已经引起分析工作者的广泛关注。本工作对近年来ICP-MS技术与各种分离手段联用，在食品中砷、硒及锡等元素形态分析中的应用进行了综述，指出了ICP-MS 相关联用技术应用于食品元素形态分析时存在的问题，并对其未来的发展趋势进行了展望。

The Application and Development of Elemental Speciation Analysis in Foods by ICP-MS Related Hyphenated Technique

Inductively coupled plasma-mass spectrometry (ICP-MS) was applied widely in elemental analysis for foods samples in advantage of the merits of low limit detection and simultaneous determination for more elements. With the development of the analytic technique, and as physical, chemical, nutritional and poisonous properties varies obviously due to the concrete elemental speciation, speciation analysis for elements was attracted attention of most analysts. ICP-MS determination coupled with all kinds of separation techniques was improved rapidly in elemental speciation analysis application for foods，including arsenic, selenium, tin, etc. This article simply summarized the domestic and foreign development and application of elemental speciation analysis for foods using ICP-MS related hyphenated technique.
