Fusion machine is a laboratory sample preparation instrument that uses the glass melting method to prepare glass frit for analysis by AAS, ICP, and X-fluorescence. When using this instrument, the mineral effect and the enhanced absorption effect of the substrate are basically eliminated, and this machine also has the advantages of high precision and accuracy of measurement. The heating methods used for high-temperature melting are gas heating, resistance radiation heating, and high-frequency induction heating.

The types of samples that can be processed by fusion machines generally include oxides, sulfides, and silicates such as mining ores, metallurgical ores, concentrates, etc. The fusion machine can also be used in universities and research institutes, or for quality control, such as glass and ceramics industry, steelmaking iron ore, blast furnace slag, bauxite, alumina, metals like Pb, Zn, Cu, Ni, sulfides, silica slag, molten slag, ore sand industry, cement, lime, kiln brick industry, etc.
