Micromeritics has launched the Asap 2050 Xtended pressure sorption analyser (xPSA), an easy-to-use instrument capable of collecting adsorption data in an elevated-pressure environment.
Pressure swing adsorption (PSA) processes rely on the fact that under pressure, gases tend to be attracted to solid surfaces.
Different gases tend to be attracted to different solid surfaces more or less strongly.
As a result, PSA processes are widely used for gas separation and purification.
For example, green technology research employs PSA to capture carbon dioxide from coal-fired power plants in order to reduce greenhouse gas production.
PSA is utilised by the medical industry to separate and produce high-purity oxygen from air.
The Asap 2050 xPSA is designed to characterise zeolites and novel new materials such as metal organic frameworks and other crystalline materials used in PSA processes.
Rapidly obtained isotherms using a range of gases and the heat of adsorption are routinely determined from this characterisation.
The ASAP 2050 analysis manifold is equipped with a pressure transducer capable of operating from vacuum to 10 atmospheres.
The instrument may be used with a variety of gases including: methane, ethane, ethylene, propane, propylene, butane, carbon dioxide, carbon monoxide, nitrogen, oxygen, argon, and nitrous oxide.
Retaining many design elements of Micromeritics's Asap 2020, the Asap 2050 includes two independent vacuum systems that allow simultaneous preparation of two samples and analysis of another.
Sample preparation and analysis can occur concurrently without interruption and without the risk of cross-contamination.
In addition to controlling the instrument's operation, Windows software also reduces the raw data collected during the analysis.
An interactive reporting system includes a versatile graphic user interface for custom presentation of results.
The standard Asap 2050 system offers a variety of reports, including DFT (Density Functional Theory), BET surface area, pore size distributions, and isotherm cycling.
