电感耦合等离子体是近十多年来迅速发展起来的溶液多元素同时测定,最有前途的激发光源之一。国内外已有不少评论文章比较系统地阐述了电感耦合等离子体发射光谱的独特优点。本文不再赘述。 毫无疑问,激发温度和电子密度是支配等离子体激发机理的主要物理参数。最近已有一些关于在等离子体中引入分析物质,研究激发温度和电子密度的报道。关于这些参数与有关电感耦合等离子体性质的理论处理也有所讨论。本文将介绍一些通用的实验测定计算方法。
Inductively coupled plasma (ICP) is one of the most promising excitation light sources that has been rapidly developed in the last ten years for the simultaneous determination of multiple elements in solution. Many domestic and foreign commentaries have systematically expounded the unique advantages of inductively coupled plasma emission spectroscopy. This article will not repeat them. Undoubtedly, the excitation temperature and electron density are the main physical parameters governing the plasma excitation mechanism. There have been recent reports of the introduction of analytes into plasmas and the study of excitation temperature and electron density. The theoretical treatment of these parameters and the nature of inductively coupled plasma is also discussed. This article will introduce some common experimental determination calculation method.
