ChemiSorb series analysers from Micromeritics provide economical and upgradeable chemisorption and physisorption analyses, suitable for teaching and research applications where lab funding is low.
The basic ChemiSorb 2720 makes chemisorption (percent dispersion, active metal area, crystallite size and surface acidity) and physisorption (single-point BET surface area, Langmuir surface area and total pore volume) analyses affordable in modestly-funded laboratories where owning an instrument had once been impractical.
The instrument features dual ports, one for analysis and one for sample preparation.
Standard features include a built-in sample cell cooling fan, four carrier-gas inlets, a preparation-gas inlet and the optional capability to accommodate a mass spectrometer or other external detector.
If analytical needs grow, the basic system can be upgraded to provide more capability.
The ChemiSorb 2750 allows the same analyses as the 2720 with the added advantages of higher precision, faster throughput and more convenience in accommodating a variety of experiments.
Possible contamination of a prepared sample by exposure to the atmosphere is eliminated by dual-function sample ports that can either be used as a sample analysis port or degas port.
The instrument also includes an injector loop valve, in which loops are easily exchangeable to provide different injection volumes.
Three built-in preparation-gas inlets and four carrier-gas inlets are included.
An optional ChemiSoft TPx System, a temperature-programmed controller and software, expands the capability of the ChemiSorb 2720 or 2750 to include: multipoint BET surface area; temperature-programmed reactions; data archiving; and advanced options in data reduction and reporting.
