Product Description:
The analyzer refers to ISO9277, ISO15901 and GB-119587 standards, according to the principle of static volumetric measurement, through the mass balance equation, static gas balance and pressure measurement to test the desorption process, the test process is carried out at the temperature of liquid nitrogen. When a known amount of gas is filled into the sample tube, the pressure will drop, and the molar mass of the adsorbed gas at adsorption equilibrium is calculated. The BET surface area and Langmuir specific surface area of single and multi-point samples were calculated by using the theoretical model. The distribution of pore volume, area and total pore volume in BJH; T -- plot micropore volume and surface area, Dubinin-Astakhov micropore distribution, Horvath -- Kawazoe micropore distribution; Density function theory (DFT) and Monte Carlo (MC) aperture distribution model, etc.
Aperture Distribution Model Automatic Specific Surface Area and Porosity Analyzer Tester
Product Features
1. Modular air path design: the introduction of the design concept, the use of modular stainless steel real air path design and anti-leakage measures, so as to ensure the realization of high vacuum, avoid the abuse of too much easy leakage due to the connection of pipeline joints.
2.Constant temperature: Because of its 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 avoid the defects of fragile and unmovable glass dewar.
3.Sensors: multiple sensors and 22 bit AD conversion devices, to ensure the precision of the surface area and aperture calculation.
4.Its density function theory (DFT) and Monte Carlo (MC) pore size distribution model have established the leading position in the specific surface area and porosity analyzer industry in China, and are also at a high level in the world.
5. Operation automation: the process of adsorption and desorption is controlled by computer without manual operation.
