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

Abstract: A method for testing an analysis apparatus that analyzes a first fluid flowing through a pipe using light that has passed through a probe attached to and disposed inside the pipe such that a portion of a light path passes outside a housing of the probe. The method includes: after a second fluid that absorbs less of the light than the first fluid has been introduced into the pipe, introducing a third fluid having predetermined absorption characteristics into the housing of the probe; and analyzing the absorption characteristics of the third fluid using the light that has passed through the probe.
