摘要

A measurement device (200) includes: a container (201) into which sample gas is to be injected; a liquefaction mechanism (210) configured to liquefy the sample gas in the container (201); a near-infrared probe (202) extending from inside to outside the container (201); and a near-infrared measuring instrument (203) configured to measure an absorbance spectrum of the sample gas in a state of being liquefied by the liquefaction mechanism (210), via the near-infrared probe (202).
