• FeaturesA highly flexible and interactive reporting system that includes an extremely versatile graphic user interface allowing custom presentation of results

Micromeritics ASAP® 2050 Xtended Pressure Sorption Analyzer is an easy-to-use instrument capable of collecting high-resolution, high-pressure adsorptive isotherms from vacuum to 10 atmospheres. While retaining many design elements of the popular ASAP 2020, the ASAP 2050 offers an extended range of capabilities that enables the instrument to obtain data in an elevated-pressure environment. The instrument also allows the user to collect traditional isotherms for determining surface area and porosity The performance of the metal hydride is characterized by its hydrogen storage capacity (adsorption) and subsequent release (desorption) of hydrogen. The adsorption capacity of alkaline-exchanged zeolites is a key parameter for the design and optimization of pressure swing adsorption processes. The active surface area and porous structure of catalysts have a great influence on production rates. The ASAP 2050 is also useful in generating surface area and porosity data for materials such as nanotubes, activated carbons, and ceramics.

• FeaturesOil-free “dry” vacuum option to prevent oil contamination,Two Independent vacuum systems that allow preparation and analysis to proceed concurrently,

Catalysts are used in a variety of applications from the production of consumer goods to the protection of the environment. Optimum design and efficient utilization of catalysts require a thorough understanding of the surface structure and surface chemistry of the active material. Chemical adsorption (chemisorption) analysis techniques provide much of the information necessary to evaluate catalyst materials in the design and production phases, as well as after a period of use. Catalytic activity is evaluated by measuring the amounts and types of reactive gas adsorbed. This volume of gas, along with an understanding of the reaction stoichiometry, is used to calculate metal dispersion, active surface area, size of crystallites, and surface acidity. Micromeritics instruments are specifically designed for the highly aggressive environment present during chemisorption analysis. Internal components are constructed of highest-quality stainless steel to prevent reactivity with most commonly used chemisorptives. Heated manifolds, gas lines, and detectors are provided to allow analysis with condensable vapors. Sample preparation occurs in situ to prevent contamination prior to analysis. Samples can be prepared at high temperatures (up to 1100 deg C) and at low pressures (

• FeaturesHigher Precision and Versatility,Optional ChemiSoft TPx System ,v

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. 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. The ChemiSorb 2720 This basic system without the TPx option makes chemisorption and physisorption analyses affordable to even the most modestly funded laboratories. The instrument rapidly and accurately performs pulse chemisorption studies and surface area analyses. The ChemiSorb 2720 features one port dedicated to performing the sorption analysis and a second port designed for sample preparation. It also features a built-in cooling fan for the sample port, 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. In addition to chemisorption experiments that include determining the percent metal dispersion, active metal area, crystallite size, and quantifying acid and base sites, a range of physisorption experiments including BET surface area, Langmuir surface area, and total pore volume can also be conducted. Hands-on calibration and dosing procedures make it an excellent teaching tool for gas-solid surface interaction studies.
