GAS ABSORPTION/EMISSION EVALUATION APPARATUS AND GAS ABSORPTION/EMISSION EVALUATION METHOD

摘要

PROBLEM TO BE SOLVED: To appropriately evaluate gas absorption/emission states to various liquid objects.;SOLUTION: A gas absorption/emission evaluation apparatus is for use in evaluation of at least one of gas absorption/emission states to a liquid object, and comprises: a sealed casing 21 with controllable temperature; a sample storage part 22 lifted in the inside of the sealed casing 21 to float by magnetism and for storing a liquid object; a magnetic floating balance 11 for measuring a weight inside the sample storing part 22; gas introduction piping 12 connected to the sealed casing 21; a vacuum pump 13 connected to the gas introduction piping 12 through a first valve 31 and for degassing the insides of the gas introduction piping 12 and the sealing casing 21; and a pressurized container 14 for liquefying and storing pressurized gas, connected to the gas introduction piping 12 through a second valve 32 and having controllable temperature.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
