摘要

PROBLEM TO BE SOLVED: To improve the efficiency of property analysis of liquefied gas. A measuring device 200 includes a container 201 into which a sample gas is injected, a liquefaction mechanism 210 for liquefying the sample gas in the container 201, a near-infrared probe 202 extending from the container 201 to the outside of the container 201, and a near infrared probe 202. A near-infrared measuring device 203 for measuring the absorbance spectrum of the sample gas in a state of being liquefied by the liquefying mechanism 210 via the infrared probe 202.
