Detailed Product Description
Material: SS304 Use For: Lab
Size: 0.35NM-500NM

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.
The Instrument adopts the one-piece valve group structure, which is effective to avoid the temperature to influence the results of analysis. Intelligent type of liquid nitrogen consumption error calculation method can
avoid the liquid nitrogen level drop to influence analysis of the structure.

 

Theory

 

Under the condition of small gas partial pressure, only a small amount of gas can contact with the sample surface, and then absorbable molecule can move freely on the surface, more and more absorbable molecule can
form a membrane on the surface of the sample, the specific surface of the sample can calculate according to the BET and the Langmuir theory.
By increase the gas pressure, the surface will form a multilayer adsorption,the multilayer molecules will form the internal condensation phenomenon in some holes,which known as capillary condensation. Because the methods like BJH can calculate the aperture, pore size distribution can easily get. When adsorption equilibrium pressure tends to saturation, the holes is completely filled with adsorbate. At this moment, the total entrances and the average entrance can be calculated and the adsorption isotherm can be drawn.
If stripping followed by adsorption saturation, the gas pressure can gradually reduce, thereby the adsorption can strip off from the hole slowly, and stripping isotherm can be drawn. According to the nature of the isothermal adsorption, stripping and formation of the hysteresis loop can determine the type.of pore structure and adsorption.
