PMI BET Sorptometers
What are PMI BET Sorptometers
Sorptometers are instruments capable of measuring surface areas of porous materials, chemisorption of gases and vapors by materials, and volume of small pores as a function of diameter. Surface area is computed from the amount of vapor adsorbed at a pressure much less than the equilibrium vapor pressure. Chemisorption of a chemical is obtained from the amount of vapor adsorbed at the desired pressure. Pore volume and diameter of pores are obtained from the amount of vapor condensed in pores as a function of vapor pressure.
Various models of sorptometers possess unique features such as multiple sample chambers, detection of chemical adsorption of a variety of chemical species, ability to use many gases, capability for water vapor adsorption, low adsorption pressures, rapid measurement of surface area, means to measure low surface area, extended accuracy, and various test modes.
