固体进样是ICP-AES试样引入系统的薄弱环节,也是当前极感兴趣的热门课题。直至目前,固体试样引入ICP的方式已相当繁多,但其实际应用远不如溶液法那样成熟。粉末法和溶液法有着各自的优点和缺点。本文提出一种卤化蒸发装置,并以卤化反应电弧蒸发粉末试样的手段,试图解决粉末法ICP-AES所存在的问题。 Solid sample injection is the weak link of ICP-AES sample introduction system, and it is also a hot subject that is of great interest at present. Up to now, the introduction of ICP into solid samples has been quite diverse, but its practical application is far less mature than the solution method. Powder and solution methods have their own advantages and disadvantages. In this paper, a halogenated evaporation device is proposed. In order to solve the existing problems of ICP-AES by powder method, the sample is evaporated by halogenated arc evaporation.
