Abstract:
A gas collecting method for collecting the gas generated from within a disk apparatus, comprising:housing a disk apparatus having an open inner structure and a collector liquid in a hermetically sealed collecting container; heating the disk apparatus and the collector liquid to a certain collecting temperature so as to permit a gas to be generated from the disk apparatus and to evaporate the collector liquid under the state that the inner space of the collecting container is partitioned into a first region in which is arranged the disk apparatus and a second region in which is arranged the collector liquid; releasing the partitioning between the first region and the second region and maintaining the disk apparatus and the collector liquid at the collecting temperature for a certain time, thereby bringing the vapor of the collector liquid into contact with the disk apparatus so as to collect the gas generated from the disk apparatus; lowering the temperature of the disk apparatus and the collector liquid, with the inner space of the collecting container being partitioned again into the first and second regions, so as to liquefy the vapor collecting the generated gas.
