PMI's BET Sorptometer accurately measures total surface area (via single and multi-point methods, and adsorption and desorption isotherms), mean pore size, pore size distribution, pore volume, and pore structure. PMI's BET Sorptometer can assess a wide variety of samples including powders and bulk solids, and can analyze both micropores and mesopores.

Tests

  • Mean Pore Size
  • Desorption
  • Pore Size Distribution
  • Chemisorption
  • Total Pore Volume
  • Pore Structure
  • Single Point Surface Area
  • Adsorption

    • Applications

    Volumetric and continuous-flow methods are utilized to characterize samples for the physical properties named under the Tests section. For all precision volumetric instruments, the equilibrium volume of a gas adsorbed on a sample can be determined by measuring the decrease in pressure of a known volume of adsorbate gas at a controlled pressure and temperature. This decrease in pressure is the result of the expansion of the adsorbate gas as it is released from the manifold to the sample cell and from gas actually adsorbing on to the sample.

    Principles of Instrument Operation

    PMI's BET Sorptometer has a multitude of applications in industries worldwide. Industries that utilize the versatile BET Sorptometer include the automotive, battery, and pharmaceutical. Specific applications include the characterization of catalysts in the chemical industry, pulp characterization in the paper industry, and testing of the powder pre-cursors to predict adhesion and final porosity in the powder metallurgy industry.
