Description
technical field [0001] The invention belongs to the category of detection equipment and relates to an element spectrum analysis method, in particular to a portable rapid element composition analyzer. Background technique [0002] At present, the elemental analysis and detection technologies in my country's metallurgical industry, site exploration, environmental protection testing and other industries are still dominated by ICP spectroscopic analysis, X-ray fluorescence analysis and atomic absorption method. Although these methods can accurately analyze the element content in the sample, the sample needs to be pretreated before the analysis, the operation technology is complicated, time-consuming, a lot of manpower and material resources are wasted, and even personal safety is endangered. Therefore, the application and promotion of a portable rapid elemental composition analyzer will have a significant and far-reaching impact on our testing industry. Contents of the inventi...
