BSD-MGC 18

The system offers fully automated gas adsorption analysis with seamless multi-gas selection and switching for accurate, repeatable results. Precise gas dosing using calibrated volumes, combined with integrated pressure monitoring and control, ensures stable adsorption measurements. Automated sequences support helium free-space measurement, nitrogen BET/BJH analysis, argon micropore analysis, and CO₂ ultramicropore characterization at 273 K, with built-in purging, evacuation, and venting for smooth operation.

With dedicated analytical channels, the system supports N₂ for surface area and isotherms, He for calibration, Ar for micropore analysis, and CO₂ for ultramicropore evaluation. Optional gases such as H₂, CH₄, and Kr expand analytical flexibility, making the system suitable for a wide range of research and industrial material characterization applications.
