近20年来,微量元素的研究有了迅速的发展。大量的工作在于研究微量元素的生物学效应,因此使营养学和毒理学方面的研究也取得显著进展。这些成就在一定程度上要归于微量元素的分析测定方法的不断进展。对于测定生物组织中的微量元素,主要应考虑灵敏度和选择性。当然快速、简单、廉价,测定范围广以及同时测定多种元素的能力也很重要。但是没有任何单一的技术能满足所有元素对这些指标的要求。通常用于分析生物样品中微量元素的是原子和核光谱以及 In the past 20 years, the research of trace elements has developed rapidly. Much work has been devoted to studying the biological effects of trace elements and therefore notable advances in nutrition and toxicology research. To a certain extent, these achievements are due to the continuous development of analytical methods for the determination of trace elements. For the determination of trace elements in biological tissues, the main sensitivity and selectivity should be considered. Of course, fast, simple, cheap, wide range of measurement and the ability to simultaneously determine a variety of elements is also very important. However, there is no single technology that meets the requirements of all of these elements for these metrics. Often used to analyze trace elements in biological samples are the atomic and nuclear spectra as well
