Metrology BET Surface Area

Microtrac BELSORP MAX X Surface and Pore Analyzer

High-precision gas and vapor sorption analyzer designed for surface area and pore size distribution (0.35-500 nm) measurements along with vapor sorption studies.

BELSORP MAX X
Sample Capacity Up to 4 samples
High Precision High-accuracy free space
Low Pressure model Down to P/Po = 10-8
Multi - Sorbates N2, W2, water vapor & more upon request

System Capabilities

The BELSORP MAX X measures adsorption isotherms for surface area (down to 0.1 m2/g with N2 and 0.0005 m2/g with Kr) and pore size distribution across ultra-micro to mesopores (0.35-500 nm). It supports water vapor sorption for hydrophilicity studies and organic sorption.

AFSM (Advanced Free Space Measurement) technology compensates for free space changes, improving accuracy for samples and ultra-microporous materials to advance nanoscale R&D characterization.
