[0002] A melting sample machine is a sample preparation instrument used to prepare glass melt slices by the glass melting method to support analyses such as X-ray fluorescence analysis (XRF). The melting sample machine is mainly used to eliminate mineral effects and matrix enhanced absorption effects and provide measurement results with high precision and accuracy. Typical sample types include oxides, sulfides, silicates, etc., such as mining ores, metallurgical ores, concentrates, etc. Workers need to measure the ore weight in advance and control the crucible temperature, and perform sample melting on the ore through X-ray fluorescence analysis. If the melting sample machine cannot reduce its weighing error, it may bring a series of serious problems, which not only affect the accuracy and reliability of the equipment, but may also seriously affect the production process and product quality.
