The BELSORP MINI X can measure specific surface area/pore size distribution by volumetric gas adsorption technique.

OVERVIEW

 

The BELSORP MINI X can measure specific surface area/pore size distribution by volumetric gas adsorption technique. Microtrac MRB's unique dead volume evaluation method (AFSM) makes highly accurate and reproducible measurement free of environmental change. The analyzer measures up to 4 specimens simultaneously with the highest level of precision and reproducibility in the world and a drastic reduction in measurement time.

 

Product Features

  • High precision measurement Maximum throughput up to 4 sample
  • Significant reduction in measurement time was achieved (up to 150% compared to the previous model)
  • Equipped with gas dosing optimization function GDO
  • Automatic measurement of adsorption isotherm with minimum condition setting
  • Highly reproducible by AFSM and AFSM2
  • Adsorption isotherm measurements of various gases over a wide temperature range
  • Measurement software that can grasp the progress rate
  • Enhanced operability and maintainability
  • The world's smallest and lightest
  • Measurement range: Specific surface area; 0.01㎡/g or more (N2), Pore size distribution; 0.7-500nm (0.35~(option))
