introduction
1. The capacity of adsorption method with high temperature and high pressure, the stripping isotherm; Low temperature adsorption, stripping isotherm, specific surface and pore size analysis;
2.1 analysis station, station 1 P0, 2 degassing treatment station, a total of four;
3. The pressure range: from high vacuum to the highest 200 bar. Equipped with imported high vacuum pabs 0-1000 torr and maximum pressure of 0-200 bar double pressure sensor;
4. The temperature range from 196 ℃ to 196 ℃;
5. Equipped with 3 l long heat preservation liquid nitrogen dewar provide constant temperature bath at low temperature; Equipped with room temperature to 500 ℃ heating furnace with high temperature constant temperature program; The other optional constant temperature water bath, constant temperature oil bath;
6. Test gas, CH4, N2 and H2, CO2, CO, Ar, Kr, etc.
All imported 316 stainless steel high pressure pneumatic valve; High pressure adsorption instrument
Gas circuit system of stainless steel, full stainless steel tube, joint, adopting VCR hard-wired, stainless steel tube sample, the system maximum 30 mpa pressure;
Equipped with high purity 99.999% HE; Has HE grieve volume testing capabilities; With automatic program control HE temperature range of hot and cold area test functions; Can get higher accuracy;
8. The standard 10 ml samples of stainless steel tube; 10 ml samples of quartz tube; Large volume pipe matching samples;
9. Have independent of saturated vapor pressure (P0) test station, ensure a high accuracy cryogenic adsorption test;
10. 2 road QiZhan off with independent temperature control, with independent timing function, can support is synchronized with the test samples of different temperature and different time degassing treatment;
11. With "ordinary heating vacuum molecular diffusion model" and "molecular replacement model" two optional features; Molecular displacement models relative molecular diffusion efficiency more than 1 times, can save more than half of the pretreatment time, solve the problem of static method of sample preparation time before long;
12. Bass's original hardware principle of vortex dust pollution prevention device, combined with the software anti smoke flying programs eliminate volatile sample of analysis in high vacuum boiling phenomenon, so as to avoid the volatiles pollution valve line.
13. Bass's original liquid nitrogen level servo system, eliminate the test due to liquid nitrogen volatile liquid nitrogen level in the process of change and bring the dead volume change, improve the test accuracy;
