Binary gas adsorption measurement
BELSORP BG measures automatically the adsorption isotherms of pure gases component from the adsorbed amount of mixed gases including corrosive gases of different molecular weight under low and high pressure (max. 15MPa) and high temperature. It uses 3-position magnetic suspension balance developed by RUBOTHERM GmbH (Germany) and measures gas density for buoyancy correction simultaneously. Correction of weight zero and buoyancy can be carried out automatically in-situ during measurement. Therefore, highly stable and reliable data can be obtained even in a long measurement. Our original gas dosing system makes it possible to measure under any desired equilibrium pressure
