Features: 1. Volumetric method of high temperature and pressure adsorption, desorption isotherm; cryogenic adsorption, desorption isotherm, specific surface and pore size analysis; 2.1 analysis stations, 1 P0 station, 2 degassing stations, a total of 4 stations; 3. Pressure range: from high vacuum up to 200bar; equipped with imported high vacuum absolute pressure 0-1000torr and maximum pressure absolute pressure 0-200bar dual pressure sensors; 4. Temperature range from -196 °C to 500 °C; 5. Equipped with 3L long insulation liquid nitrogen Dewar cup to provide a low temperature constant temperature bath; equipped with room temperature to 500 °C program temperature heating furnace to provide high temperature; another optional constant temperature water bath, constant temperature oil bath; 6. Test gas: CH4, N2, H2, CO2, CO, Ar, Kr, etc.; All imported 316 stainless steel high pressure pneumatic valve; high pressure adsorption instrument 7. All stainless steel gas system, all stainless steel pipe, joints, using VCR hard connection, stainless steel sample tube, the system maximum pressure 30MPa; Equipped with 99.999% high-purity HE; with HE dead volume test function; with automatic program control HE hot and cold zone temperature zone test function; obtain higher accuracy; 8 standard 10ml stainless steel sample tube; 10ml quartz sample tube; large sample tube matching; 9Best automatic high temperature and pressure gas adsorption instrument with independent saturation vapor pressure (P0) test station to ensure high accuracy of low temperature adsorption test; 10. The 2-way degassing station has independent temperature control and has an independent timing function, which can support the degassing treatment of the sample at different temperatures and different times simultaneously with the test. 11. It has two optional functions: "Normal heating vacuum molecular diffusion mode" and "Molecular displacement mode"; the molecular displacement mode is more than doubled in molecular diffusion mode efficiency, and can save more than half of the pretreatment time, solving the previous static method. The problem of long sample preparation time; 12.Bethard's original hardware anti-pollution device with vortex-dusting principle, combined with software-based anti-pumping program, completely eliminates the boiling-up phenomenon of volatile samples during high vacuum, thus avoiding volatiles contaminating the valve piping. 13.Bristol's original liquid nitrogen surface servo holding system eliminates the dead volume change caused by the change of the liquid nitrogen surface due to the evaporation of liquid nitrogen during the test process, and improves the test accuracy;
