Description

Specific surface area and porosity are the important physical parameter of porous materials, They are typically measured by physical
adsorption method. Under the condition of a certain cold shower, the analyzer would choose the appropriate gas adsorption,
and let the gas molecules adsorbed on the entire surface of the sample that would be tested, the indirect research of specific
surface and porosity properties of pore materials would be taken by sensors.

The basic principle of instrument is based on temperature physical adsorption instrument of static volumetric method. So the
instrument can have many data analysis such as single point, multi-point BET specific surface area, Langmuir, the BJH pore surface
area, pore distribution, total entrance and the square measure of the data analysis. Measure range of specific surface area is from
0.01 M2/g to unlimited, the range of aperture analysis is from 0.35nm to 500nm.
