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.
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.
Operating Modes
High-Precision Mode
Reference port tracking for maximum accuracy.
Multi-Sample Mode
Run up to four samples for higher throughput.
Quick BET Mode
Rapid three-point BET measurements for screening.
Vapor Sorption
Isotherms for water vapor and organic vapors (Upon request).
