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); pressure accuracy�?#177; 0.15%＇�/span>P.S（�/span>

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;
