Omnisorpt

Coultier Omnisorp 100CX

  • Area and porosity of particles by physisorption and chemisorption, static volumetric method for adsorption and desorption isotherms.
  • For example:
      • Specific surface area, pore volume and pore size distribution of solid porous materials (physisorption of nitrogen at the temperature of liquid nitrogen, 77 K).
      • Metal surface area and dispersion measurements of carrier supportted metal catalysts (chemisorption of hydrogen or carbon monoxide at temperatures near room temperature).
  • Suitability of the method for each samples, such as heating as a pretreatmet, must be discussed separately.
