Abstract: 試料ガス中の所定成分濃度を分析する分析装置に用いられる測定ユニット(1)であって、測定光を試料ガス中へ照射する照射部(21)と、測定光を受光面において受光する受光部(24)と、照射部(21)および/または受光部(24)の近傍にパージエアを導入するパージエア導入口(14)と、照射部(21)から受光部(24)までの測定光の光路上に配置され、ガスとパージエアとの温度差により生ずる熱レンズ効果によって伝搬経路が変動する測定光を受光部の受光面内に集光させる集光レンズ(23)とを備える。

Abstract: The invention relates to an instrument for in situ monitoring a degradation level of refined oil in use. Provided are: an excitation light irradiation part (1) that varies an intensity of excitation light to irradiate the excitation light on refined oil; a fluorescence intensity detection part (2) that detects an intensity of fluorescence that is generated by the irradiation of the excitation light; a time lag characteristic calculation part (33) that calculates a time lag characteristic of a fluorescence intensity variation with respect to the intensity variation of the excitation light; and a degradation index value acquisition part (35) that refers to a correlation between a degradation index value indicating a degradation level of the refined oil and the time lag characteristic to acquire the degradation index value from the time lag characteristic calculated in the time lag characteristic calculation part.
