消解方法对ICP-MS法测定人发中微量元素含量的影响

The different influence for the digestion methods to measure the content of multi-trace element in the human hair by ICP-MS

本文采用三种不同酸体系和两种加热方式组合成五种消解方法,对人发标准物质(GBW07601)进行消解,以ICP-MS作为分析技术测定其微量元素的含量,并对其方法、结果及影响因素进行了相应的讨论.

Five digesting methods concluding three digesting acid systems and two heating modes were compared and discussed for the detection of multi-trace element concentrations in the standard material of human hair (GBW07601) by inductively coupled plasma mass spectrometry(ICP-MS),evaluate the accuracy of this method.And the accuracy of different methods was evaluated.
