热化学反应炉电热蒸发装置及其在ICP-AES中的应用

THE DEVICE OF ELECTROTHERMAL VAPORIZATION WITH THEROCHEMICAL REACTION FURNACE AND EMPLOYMENT OF THE DEVICE IN ICP-AES——The New Introduction System of Solid Sample

一、引言溶液雾化进样的ICP-AES方法,虽然有许多优点,但也还存在着一些不足之处: 1.有相当一部分元素(主要是分析线为原子线的元素Hg、Se、Te、As、Sb、Bi、Cd、Sn、Pb、En、Ga、In、Ge、Tl等),检测限较差,不能满足环保、地质、冶金、化工等部门的需要。

The device of electrothermal vaporization with therochemical reaction furnace and employment of the device in ICP-AES is described bed in this report. This new introduction system of solid sample is signifieantly expanded the analy tical eapability of ICP-AES.Tke device of introduction system and analytical method of solid sample and water sample is presented in this report.
