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 2600 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.
Gold APP Instruments high pressure and high
temperature gas sorption analyzer H-Sorb 2600 adopts static volumetric
principle to determine adsorption and desorption isotherms under high pressure
(atmospheric to 200Bar) and high temperature (atmospheric to 500℃) with a stainless steel VCR manifolds
system, fully automated operation can control system and multi calculation
methods, all these guarantee H-Sorb 2600 to produce a highly repeatibility and
highly precision analysis data.
