Introduction: Gas fusion sampler is a professional sample preparation equipment for X-ray fluorescence analyzer (XRF) - glass melting plate analysis and testing. The glass frit used in the glass melting process for the preparation of XRF is a process in which the sample is in flux (borate: typically a single or a certain mixture of lithium tetraborate and lithium metaborate) and a release agent (mostly a halide). With the help of a platinum crucible (generally platinum/gold mass ratio of 95/5) as a heat-conducting vessel, it is heated and melted at a high temperature (melting sample temperature is generally between 1050°C and 1300°C), and finally the bottom of the pan is directly cooled or molded. Mold cooling formed into a glass fuse. The glass frit method, as one of the sample preparation methods for the XRF test, effectively reduces the matrix and mineral effects of ore, rock, soil, refractories, and metallurgical materials during XRF analysis, greatly improving the accuracy of the analysis, and can be widely used. Applied to iron and steel, metallurgy, chemical industry, geology, cement, ceramic refractories and other industries. The automatic melt sampler is a fully automatic 4-head gas fusion sampler. The machine has a compact structure, uses gas (propane or butane) fusion sample, fast heating speed, automatic temperature control, good temperature control accuracy, PLC automatic control, multiple design Safety protection, ensure the safe use of gas, superior performance of the whole machine, high cost performance. Features: 1. The application of advanced design concepts, small size, beautiful appearance of the structure. 2. It adopts 4 heads automatic gas sampling design and uses LPG (Propane/Butane) heating, which has a fast heating speed and a wide temperature setting range (800-1600°C). 3. Each head can be controlled independently and each heating head can be independently displayed. 4. With high temperature stability and good reproducibility, one, two, three or four heating heads can be set individually. 5. During the entire melting process, the molding die is heated independently, which greatly extends the service life of platinum. 6. PLC automatic control, high degree of automation, can be set rotation, swing, sample, pause, time and speed and other parameters, to achieve a key operation. 7. Set up a hierarchical authorization mechanism (technical engineers and technical experts) to meet the needs of hierarchical management of laboratory equipment. 8. The design includes emergency shutdown, gas leak off, overheat protection off, flame control unit lock, temperature sensor flame control and other safety mechanisms. The LED displays the running status throughout. Multiple mechanisms ensure equipment stability and personnel operation safety. 9. With high sample preparation efficiency, the quality and stability of the sample can also meet the XRF experimental requirements. The overall cost-effectiveness is superior.
