非火焰法是原子吸收分析法的一种补充。但它的灵敏度却比火焰法高出百倍到千倍,甚至可与质谱分析法、中子活化分析法相媲美,而装置并不复杂。另外,只要样品均匀,不管是固体还是液体,乃至混浊液都可以测定。基于这些特点非火焰法便能够广泛地用于冶金、地矿、化工、环境保护、医学卫生和食品等部门对微量元素的检测。但是,必须指出非火焰法干扰比较严重。因此,如何有效而精确地消除干扰,一直是分析工作者所要探求的一个主要方面。然而,迄今为止的报导都局限于个别分析问题的实验,而没有系统地研究和解释这些干扰的实质,并从理论上指导实践。由此可见,对这方面的工作仍需要继续深入和提高。
Non-flame method is a complement to atomic absorption analysis. But its sensitivity is one hundred times to a thousand times higher than the flame method, and even comparable with mass spectrometry, neutron activation analysis, and the device is not complicated. In addition, as long as the sample is uniform, whether solid or liquid, even turbid liquid can be measured. Based on these characteristics, non-flame method can be widely used in the detection of trace elements in metallurgy, mining, chemical, environmental protection, medical and health and food sectors. However, it must be pointed out that non-flame interference is more serious. Therefore, how to eliminate interference effectively and accurately has always been a major aspect sought by analysts. However, the reports so far have been limited to the analysis of individual problems, but have failed to systematically study and explain the essence of these disturbances and have theoretically led the practice. From this we can see that the work in this respect still needs further deepening and improvement.
