The H-Sorb X600 series high pressure gas adsorption analyzers adopt 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 isotherm reports.

The very flexible selection, the serially produced and customized cells and necessary accessories require detailed consultation with the vendor to determine optimum configuration with task oriented accesories.
