The HP6500 series product is a technologically advanced desktop fully automatic volumetric high-pressure gas adsorption instrument. The model of HP6500 series products is a two-station type, and the maximum pressure can reach 100bar or 200bar respectively. High-pressure gas adsorption analyzers can collect high-pressure adsorption data over a wide temperature range. Temperature control methods include a high-temperature heating pack (standard), an optional cycle temperature control system, an optional liquid nitrogen cryogenic system, or an ultra-low temperature refrigeration system option. Can be applied to adsorption research of hydrogen, methane, carbon dioxide, nitrogen, argon or any other non-corrosive gas. It can judge the gas adsorption and desorption behavior of any type of adsorbent, such as activated carbon, zeolite, templated silica, MOF, hydride film agent, etc. Detailed equations of state used by the measurement software ensure data accuracy.
