Test principle: the static volumetric method, gas adsorption;
Measuring range: surface area ≥ 0.005M2/g, no upper limit; pore size 0.35-500nm; pore volume 0.0001 cm3/g, no upper limit.
Sorption gas: N2 (high purity); Ar, Kr, CO2, CH4, etc. available
Analysis No: 2 samples tested alternately
Sample Type: powders, granules, fibers, flakes and other materials
Pressure Sensor: 1000torr (133kpa), 10torr (1.33kpa); 1torr (0.133kpa) or 0.1torr (0.0133kpa); pressureaccuracy ≤± 0.15%(P.S)
P0 tube: there is a separate P0 tube in every analysis port, two in all, controlled by a separate pressure sensor, completely separates from the analysis bit, real-time detecting the nitrogen saturation vapor pressure, and participating in the theoretical calculation; also the atmospheric input method to determinate the P0 accurately;
Cold trap tube: sample degassing system has a special cold trap device that can effectively remove the water, hazardous substances and other impurities, degassed from the special sample, and it can avoid the contamination of the vacuum system;
Degassing system: two samples can be analyzed simultaneously, also can be degassed in the original port; another with two separate sample degassing station, which is independent and separate from the sample analysis. Throughout the degassing system, there are two independent heating packages, two independent temperature control systems, which can be programmed by temperature control; you can choose another four external vacuum degassing pretreatment system;
Degassing temperature: room temperature -400℃, accuracy ± 1℃;
Test Efficiency: multi-point BET surface area--30 minutes per sample; Determination micro pore size distribution from adsorption and desorptionisotherms_5-20h per sample.
Nitrogen Partial Pressure: P/Po 1×10-8 _ 0.998, the minimum resolvablerelative pressure 5 × 10-7
Ultimate vacuum:≤ 10P-6 Pa (7.5×10-9 torr)
Measurement Accuracy: ≤±1.0%(surface area); ≤0.01nm(the most frequency micro pore) ≤±0.04% (True density);≤±1.5% (STSA)
Operation Mode: Automatic
测试原理:静态容量法,低温氮吸附(或其他吸附气体);
测试精度:≤± 1.0%(比表面);≤0.02nm(最可几孔径);
测试气体:氮、氧、氢、氩、氪、二氧化碳、甲烷等 ;
测试范围:0.0005(m2/g)--至无上限(比表面积);2nm-500nm(介孔及大孔分析);0.35nm-2nm(微
孔分析);孔体积0.0001cm3/g-至无上限;
