Surface Area and Porosity Analysis

The BELSORP-max is a high-end volumetric gas adsorption instrument. The BELSORP-max can measure up to 3 samples simultaneously offer high throughput at the same time as high-resolution analysis.
To obtain useful information about micropore, it is important to measure adsorption isotherm from low relative pressure with accuracy. The BELSORP-max is designed for wide range adsorption isotherm for surface area and pore size distribution analysis. It can measure adsorption isotherms from relative pressure as low as 1 x10-8 (N2 at 77K, Ar at 87K), using a 13.3Pa pressure transducer.
Also AFSM, the new method for free space measurement, is applied and adsorption isotherm can be measured with high accuracy. Chemisorption option enables unattended chemisorption measurement from pretreatment with step programs.
