Product Features

1、WBL Reference for series fully automatic specific surface area and porosity analyzers ISO9277、ISO15901 International standards and GB-119587 National standards are based on the static capacity method measurement principle, and the adsorption and desorption process is tested through mass equilibrium equation, static gas equilibrium and pressure measurement, and the test process is carried out at liquid nitrogen temperature. It is known that after the amount of gas is filled into the sample tube, the pressure will drop, thereby calculating the molar mass of the adsorbed gas during adsorption equilibrium. Through the measured equilibrium adsorption amount, the theoretical model is used to calculate the single point and multi-point of the sample to be tested. BET Specific surface area, Langmuir Specific surface area； BJH Mesoporous pore volume, area distribution, total pore volume； t―plot Micropore volume and surface area, Dubinin―Astakhov Micropore distribution, Horvath―Kawazoe Micropore distribution； Density function theory ( DFT） and Monte Carlo ( MC） parameters such as pore size distribution model.

2、Modular gas circuit design 

WBL The series of fully automatic specific surface area and porosity analyzers introduce the most advanced design concept in the world today, adopting a unique modular all-stainless steel vacuum circuit design and advanced anti-leakage and pollution-free measures, thus ensuring the realization of high vacuum and avoiding the disadvantage of leaking due to too many connecting pipe joints.

3、Constant temperature

Due to its unique internal structural design, the metal dewar bottles can store liquid nitrogen for more than ten days. During the experiment, there is almost no loss of liquid nitrogen, thus ensuring the constant temperature of the sample being tested, while avoiding the defect that the glass dewar bottle is fragile and not moving.

4、High-precision sensor

Multiple high-precision sensors and 22-bit AD The conversion device ensures the accuracy of specific surface area and pore size calculation.

5、Advanced theoretical model

Its advanced density function theory ( DFT） and Monte Carlo ( MC） The pore size distribution model establishes its dominant position in my country's specific surface area and porosity analyzer industry, and is also at the leading level in the international market.

6、Operation automation

The adsorption and desorption process are all controlled by computers without manual operation
