INESA INESA WBL-820 Automatic specific surface area and porosity analyzer

WBL series automatic specific surface area and porosity analyzer refers to the ISO9277, ISO15901 international standards and GB-119587 national standards, according to the static volume method measurement principle, through the mass balance equation, static gas balance and pressure determination to test the adsorption and desorption process, the test process is carried out at the temperature of liquid nitrogen. It is known that when a large amount of gas is filled into the sample tube, the pressure drops, and the molar mass of the adsorbed gas at adsorption equilibrium is calculated. Through the measured equilibrium adsorption capacity, the theoretical model was used to find the specific surface area of single-point and multi-point BET and the specific surface area of Langmuir of the measured sample. BJH mesoporous and macroporous volume 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) pore size distribution model.

Features

(1) Modular air path design: WBL series automatic specific surface area and porosity analyzer introduces a professional design concept, adopts a unique modular all-stainless steel vacuum air path design and professional anti-leakage and pollution-free measures, so as to ensure the realization of high vacuum and avoid the drawbacks of easy leakage due to too many connecting pipeline joints.

(2) Constant temperature: Because of its unique internal structure design, the self-developed metal dewar can store liquid nitrogen for more than ten days, and there is almost no loss of liquid nitrogen during the experiment, so as to ensure the constant temperature of the tested sample, and at the same time avoid the defect that the glass dewar is fragile and not suitable for moving.

(3) High-precision sensors: Multiple high-precision sensors and 22-bit AD conversion devices ensure the accuracy of specific surface area and aperture calculation.

(4) Professional theoretical model: its professional density function theory (DFT) and Monte Carlo (MC) pore size distribution model have established a leading position in CHINA's specific surface area and porosity analyzer industry, and are also at a high level in the world.

(5) Operation automation: the adsorption and desorption processes are all controlled by the computer, and no manual operation is required.
