Quantachrome AUTOSORB II (LS123)

Gas sorption analyzer

Fully automated volumetric gas adsorption station

The device is dedicated to standard characterization measurements of nano-structured matter by nitrogen sorption isotherms at 77K. The system is equipped with a micropore analysis option and two outgassing stations for temperatures up to 350°C. The instrument data reduction sofware supports the standard data reduction algrorithms like BET, BJH, etc. as well as older  DFT kernels for typical pore geometries.



  • Fully automated
  • High resolution pressure measurements from 0.01 mbar to 1000 mbar
  • Data reduction software with BET-, DFT-, (and micropore analysis)
  • 2 Outgassing stations
