ASAP 2050 XP Xtended Pressure Sorption Analyzer
Superior Performance Under Extended Pressure
The fuel cell and its chemical energy source, hydrogen, have received much recent attention as a promising long-term solution to the world’s energy needs. Developing storage technologies involving advanced materials and the conversion of hydrogen to useful forms of energy are of critical importance. A fundamental understanding of hydrogen physisorption/chemisorption processes and adsorption/desorption kinetics is needed to optimize hydrogen uptake and release capacity rates
The HPVA II Series of adsorption analyzers from Particulate Systems uses the static volumetric method to obtain high-pressure adsorption and desorption isotherms utilizing gases such as hydrogen, methane, and carbon dioxide. The volumetric technique consists of introducing [dosing] a known amount of gas [adsorptive] into the chamber containing the sample to be analyzed.
When the sample reaches equilibrium with the adsorbate gas, the final equilibrium pressure is recorded. These data are then used to calculate the quantity of gas adsorbed by the sample.
The Selective Adsorption Analyzer SAA 8100 is a gas delivery system based upon the technology of PID Engineering and Technology, a Micromeritics company. The primary components of the system include mass flow controllers, blending valves, vapor sources, temperature control, and a simple column for evaluating adsorbents. The basic procedure for evaluating an adsorbent candidate includes: activation (degassing) of the adsorbent, flow a mixture of gases (or vapors) through the column containing the adsorbent, and monitor the composition of the effluent gas from the column containing the adsorbent.
