H-Sorb ***0 high pressure gas adsorption volumetric
principle analyzer introduction
Gas sorption analysis is important in many fields of materials,
such as energy storage materials, improved catalysts for
petrochemical processing, advanced pharmaceuticals and food
industries. At present, there is tremendous interest in the
development of innovative materials for the transition to renewable
energy. The science of gas sorption has become particularly
critical in the advancement of materials for storing fuel gases
such as hydrogen or natural gas, as well as for sequestration of
greenhouse gases.
The H-Sorb ***0 high pressure gas sorption analyzer adopts the volumetric technique principle which consists of dosing a known amount of gas adsorptive into measurement tubes where lying samples (such as zeolites, carbon nanotubes, rocks, catalysts, activated carbons, molecular sieve, hydrides etc. ) to be analyzed. When samples reach equilibrium with the adsorbate gas (such as hydrogen, methane, carbon dioxide, nitrogen, argon, krypton etc.), detailed and comprehensive final equilibrium pressures will be recorded automated by Gold APP Instruments company dedicated and patented software. These data are used to calculate the quantity of gas adsorbed by samples. This measurement procedure automatically repeated by software under given temperature and pressure intervals until finalized the maximum preselected pressure. Finally, each of the equilibrium points volume adsorbed, equilibrium pressure, absolute pressure etc. data are plotted to produce the isotherm. By using the isotherm data, operators can calculate further more information such as Langmuir fitting isotherm, the adsorption rate curve, PCT (pressure-composition-temperature) or PCI (pressure-composition-isotherm) curve etc.
Pressure-Composition Isotherms (PCI) and Pressure-Composition Temperature (PCT) is one of the most informative sorption measurements. The result is a plot of the equilibrium absorbed gas concentration in the material as a function of pressure and temperature.
