BELSORP MAX G


The BELSORP MAX series has been extended by a powerful, compact and cost-effective model. The BELSORP MAX G is a special instrument for measuring porous / non-porous material in the micro- to macroporous range (BET specific surface area / pore size distribution) and features one sample port.





FEATURES


- BET and PSD from micro to meso and macropores by gas adsorption measurement of N2 (77.4K), Ar (87.3K)

- Low BET specific surface area by Kr gas measurement at 77.4K

- High performance PSD analysis by GCMC・NLDFT in BELMaster Version 7

- Actual and short time evaluation for each adsorption point by gas dosing optimization (GDO) function




TYPICAL APPLICATIONS


Used in various fields such as catalysts, batteries, fibers, polymer materials, chemicals, pigments, cosmetics, magnetic powder,

separation membranes, filters, toner, cement, ceramics, semiconductor materials, etc.
