Description

Test principle: the static volumetric method, gas adsorption;
Analysis Models: BET, Langmuir, BJH, t-plot, DR, ?s-plot, MP, HK, SF, and NLDFT;
Measuring range: surface area ? 0.**5M2/g, no upper limit; mesoporous and macroporous 2 _ **0nm; micropore size 0.*5nm _ 2nm; pore volume 0.***1 cm3/g, no upper limit.
Sorption gas:N2 (high purity); Ar, Kr, CO2, CH4, etc. available
Analysis Stations: 2 ports. One analysis station can test the micropore and the other can test the mesorpore.
Sample Type: powders, granules, fibers, flakes and other materials
Pressure Sensor: ***0torr (**3kpa), *0torr (1.*3kpa); 1torr (0.**3kpa) or 0.1torr (0.***3kpa); accuracy? 0.*5%?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 port, 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: Parity, ectopic vacuum degassing pretreatment systems are controlled by separate pressure sensors. Two samples can be analyzed simultaneously, also two samples can be degassed in degassing ports; two independent sample degassing stations are separate from the sample analysis ports. The degassing system has 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 ***0?, accuracy 1?;
