Description

Multi-station multifunctional high-frequency sample melting machine Technical Field The utility model relates to the technical field of glass fuse sample preparation, in particular to a multi-station multifunctional high-frequency sample melting machine. Background The X-ray fluorescence spectrum analysis method is commonly used for measuring major elements and trace elements in samples such as powder metallurgy, geological mineral products and the like, and two sample pretreatment modes are commonly adopted, namely a powder tabletting method and a melting sample preparation method. The powder tabletting method is to put the dried or roasted and ground powder sample into a special mould, and press the powder sample into a sample sheet under a certain pressure. The melting sample preparation method is to mix a dried, ground and uniformly mixed powder sample with a flux, then place the mixture in a special crucible (a platinum crucible made of an alloy with 95% of Pt and 5% of Au is usually adopted), heat and melt the mixture at a high temperature of 1000-1200 ℃ and cool the mixture to obtain a smooth and flat glass sample. The powder tabletting method has a very serious matrix enhanced absorption effect, so that the error is larger, and the powder tabletting method is mainly used for the production process control and semi-quantitative analysis of enterprises at present. The fusion sample preparation method can effectively eliminate the enhanced absorption effect and mineral effect of the matrix, and greatly improve the accuracy of the test, so that the fusion sample preparation method is popularized and applied in more and more fields.
