Introduction: The instrument adopts self-developed patented technology (one-button start self-locking safety sliding door design), which can resist accidental explosion and microwave leakage, and improve the risk of microwave leakage caused by the loosening of the traditional door opening structure. The stainless steel microwave resonant cavity can accommodate a variety of digestion tanks and process 1-6 samples; at the same time, it is equipped with full tank PT100 platinum resistance probe temperature measurement and full tank pressure monitoring functions, non-pulse continuous microwave output, high-frequency closed-loop feedback Control and other means can accurately control the progress of the microwave chemical reaction. It is suitable for the accurate determination of trace, trace and ultra-trace elements in various samples by atomic spectroscopy such as atomic absorption spectrometer, ICP-emission spectrometer, atomic fluorescence spectrometer, ICP-mass spectrometer, and anode stripping instrument. Features: 1. Adopt a large furnace cavity design with completely independent intellectual property rights, which can place 1~6 100ml ultra-high pressure digestion tanks at the same time; 2. Using the British Cambridge magnetron (warranty 5 years) and professional uniform furnace cavity (microwave resonant cavity); industrial-grade 1000W magnetron to ensure long-term stable operation of the instrument; 3. Temperature and pressure dual measurement and control, precise control, and actively prevent over-temperature and over-pressure; 4. The high-precision anti-interference air guide pressure sensor adopts the ideal gas control method to directly measure the actual reaction pressure in the digestion tank. The pressure measurement range is 0-10 MPa, and the pressure measurement accuracy is 0.01 MPa; 5. The plug-in high-sensitivity platinum resistance temperature sensor can directly measure the actual reaction temperature in the digestion tank. The temperature measurement range is 0~300℃, and the temperature measurement accuracy is ±0.1℃; 6. The pressure and temperature in any reaction tank can be measured and controlled, and the chemical reaction process can be accurately displayed; 7. A variety of materials and different capacities can be selected, and can be equipped with a perfluorinated digestion tank or FT double-layer digestion tank: the inner tank of the FT digestion tank is made of PTFE (polytetrafluoroethylene), and the sheath is made of fully imported PEEK one-time die-casting , Resistant to high temperature, high pressure, and strong acid corrosion; easy disassembly and assembly, fast cooling; double pressure relief protection digestion tank with air vent and sealed bowl; up to 6 ultra-high pressure digestion tanks can be placed at the same time at one time; furnace cavity ventilation adopts acid corrosion resistance, Centrifugal fan with large air volume, exhaust air volume 5m3/min; 8. The patented technology is specially designed to start the self-locking ground-moving safety sliding door with one button, which can resist accidental explosion and microwave leakage.
