等离子炬管是电感耦合高频等离子体光源的核心组件,它的几何形状、结构参数和工作伏态直接影响和决定着ICP发射光谱分析的分析性能(元素检出能力、分析精密度)、气流的消耗量以及操作是否方便。尤其是在如何节省耗气量和扩大炬管的多功能性方面,越来越受到人们的关注,炬管的改进和最新设计竞相出现,并常常作为评价各种ICP分析装置的依据之一。 Plasma torch is the core component of inductively coupled high-frequency plasma source. Its geometry, structural parameters and working voltage directly influence and determine the analytical performance of ICP emission spectrometry (element detection ability, analytical precision), gas flow The consumption and ease of operation. In particular, it is attracting more and more attention on how to save gas consumption and expand the versatility of the torch. The improvement of the torch and the latest design are competing and often serve as a basis for evaluating various ICP analysis devices.
