h-sorb 2600 high pressure gas adsorption volumetric principleanalyzer introduction
gas sorptionanalysis is important in many fields of materials, such as energystorage materials, improved catalysts for petrochemical processing,advanced pharmaceuticals and food industries. at present, there istremendous interest in the development of innovative materials forthe transition to renewable energy. the science of gas sorption hasbecome particularly critical in the advancement of materials forstoring fuel gases such as hydrogen or natural gas, as well as forsequestration of greenhouse gases.
the h-sorb 2600 high pressure gas sorption analyzer adoptsthe volumetric technique principle which consists of dosing a knownamount of gas adsorptive into measurement tubes where lying samples(such as zeolites, carbon nanotubes, rocks, catalysts, activatedcarbons, molecular sieve, hydrides etc. ) to be analyzed. whensamples reach equilibrium with the adsorbate gas (such as hydrogen,methane, carbon dioxide, nitrogen, argon, krypton etc.), detailedand comprehensive final equilibrium pressures will be recordedautomated by gold app instruments company dedicated and patentedsoftware. these data are used to calculate the quantity of gasadsorbed by samples. this measurement procedure automaticallyrepeated by software under given temperature and pressure intervalsuntil finalized the maximum preselected pressure. finally, each ofthe equilibrium points’ volume adsorbed, equilibrium pressure,absolute pressure etc. data are plotted to produce the isotherm. byusing the isotherm data, operators can calculate further moreinformation such as langmuir fitting isotherm, the adsorption ratecurve, pct (pressure-composition-temperature) or pci(pressure-composition-isotherm) curve etc.
pressure-composition isotherms (pci) andpressure-composition temperature (pct) is one of the mostinformative sorption measurements. the result is a plot of theequilibrium absorbed gas concentration in the material as afunction of pressure and temperature.
gold app instruments high pressure and high temperature gassorption analyzer h-sorb 2600 adopts static volumetric principle todetermine adsorption and desorption isotherms under high pressure(atmospheric to 200bar) and high temperature (atmospheric to500℃) with astainless steel vcr manifolds system, fully automated operation cancontrol system and multi calculation methods, all these guaranteeh-sorb 2600 to produce a highly repeatibility and highly precisionanalysis data.
