一、前言众所周知,感应耦合等离子体光源(ICP)具有许多优点,然而,由于复杂的化学前处理和雾化系统带来了不少问题,主要的有如下几点:(1)溶样问题:有的试样难于溶解或溶解不完全;有的试样虽然能溶解,但在溶解过程中有的元素被严重地挥发损失。如果用碱熔,一方面容易使试样沾污,另方面带入大量盐类,容易堵塞喷雾器与消耗 ICP 的激发能 I. INTRODUCTION It is well-known that inductively coupled plasma (ICP) light sources have many advantages. However, due to complex chemical pretreatment and atomization systems, many problems have arisen. The main points are as follows: (1) Solubility problems: Some samples are difficult to dissolve or dissolve incompletely; while some samples can dissolve, some elements in the dissolution process are severely volatilized and lost. If the use of alkali melting, on the one hand easy to make the sample stained, on the other hand bring a lot of salt, easy to plug the sprayer and consume ICP excitation energy
