  • The ChemiSorb 2720 and ChemiSorb 2750 can be equipped to perform chemical and physical absorption tests that are central to the development, testing, and production of catalysts. They employ the dynamic (flowing gas) technique of analysis by which the quantity of gas taken up by the sample or released from the sample surface is monitored by a Thermal Conductivity Detector (TCD). Data obtained by the instruments can be used to calculate key parameters for catalyst characterization: metal dispersion, active surface area, BET surface area, average crystallite size, surface acidity or basicity, and activation energy via first order kinetic models.
