BET Adsorption Test

Product Name BET Adsorption Test Product Overview English Introduction: BET adsorption test is an internationally recognized core detection technology for characterizing specific surface area, pore size distribution and pore volume structure in the material field. Based on the low-temperature nitrogen adsorption principle, it accurately calculates key pore structure parameters such as material specific surface area, mesopore/micropore size distribution, pore volume and adsorption constants by measuring gas adsorption and desorption isotherms of materials under different relative pressures, serving as a standard method for porous material performance evaluation. This testing service is equipped with Micromeritics TriStar II Plus 3030 fully automatic specific surface area and porosity analyzer from the United States, supporting two testing modes: professional mesopore test and full-pore (micropore + mesopore) full-range test, suitable for the detection of various porous powder materials. With high detection accuracy and strong data stability, the instrument can accurately meet the analysis requirements of trace specific surface area and multi-stage pore structure. It is widely applied in new energy materials, catalytic materials, adsorption materials, ceramics, carbon materials, polymer porous materials and other fields. The detection data complies with national standards and ASTM international standards, supporting academic paper publication, new material R&D, product performance optimization, industrial quality inspection and project conclusion application.
