The ChemiSorb 2720 and ChemiSorb 2750 can be equipped to perform chemical and physical adsorption tests that are central to the development, testing, and production of catalysts. ChemiSorb 2720 and 2750 apply the dynamic chemisorption method, employing a high sensitivity Thermal Conductivity Detector (TCD)  for the accurate quantification of the gas chemisorbed by the catalyst.  Chemisorption data are reliably converted to catalysts key parameters : metal dispersion, active surface area, , average crystallite size, surface acidity or basicity, and activation energy. In addition, catalysts can be tested in situ by a rapid BET total surface area measure, monitoring possible changes in the sample microstructure. The ChemiSorb 2720 is an entry level chemisorption and physisorption analyzer ideal for pulse chemisorption,  single point BET surface area and total pore volume measurements. ChemiSorb 2720 features a single port dedicated to sorption analysis and a second independent port designed for sample preparation. It also features a built-in cooling fan to accelerate the sample cooling after a high temperature activation, four carrier gas inlets, one prep gas inlet, and the optional capability to accommodate a mass spectrometer or other external detector attached at the exhaust port. Hands-on calibration and dosing procedures make it an excellent teaching tool for gas-solid surface interaction studies. The ChemiSorb 2750 has been further enhanced with the addition of an injection loop valve for pulsing active gases on the catalyst and features an enhanced dual-port design that allows in-situ preparation and analysis of two samples.
