摘要
An apparatus for measuring gas absorption isotherm is provided to precisely adjust the amount of standard gas by using a space volume between valves. An apparatus for measuring gas absorption isotherm comprises a measurement system including a vacuum valve and a vacuum pump, a temperature maintaining system, an automatic control system and a computer system. The temperature maintaining system uses liquid refrigerant and a heater to maintain a sample container in a constant temperature. The automatic control system controls the measurement system and the temperature maintaining system, and transmits measured pressure and temperature to a computer. Sample containers(S1,S2) are connected to valves(V6,V7). The sample containers are heated, and a vacuum pump operates to exhaust substance detached from a sample.
