ANALYZER AND ANALYSIS METHOD IN PURIFICATION SYSTEM OF MIXTURE CONTAINING ORGANIC SOLVENT AND WATER, AND THE PURIFICATION SYSTEM

To provide an analyzer capable of analyzing the quality of a mixture to be received or an organic solvent to be discharged without stopping the reception of the mixture containing the organic solvent and water and the discharge of the purified organic solvent.SOLUTION: First and second containers 101a, 101b each capable of storing a liquid to be analyzed are connected to a supply line of the liquid to be analyzed in a switchable manner. A first circulation line that forms a circulation pathway of the liquid to be analyzed together with the first container 101a and a second circulation line that forms a circulation pathway of the liquid to be analyzed together with the second container 101b are arranged to be switchable. The liquid to be analyzed in the circulation pathway is analyzed by analytical means 505, 506, 507. The supply line and the circulation line forming means are configured to be switched so that one of the first container 101a and the second container 101b is connected on the supply line as a receiving container, and the other is an analytical container forming a circulation pathway.SELECTED DRAWING: Figure 2 【課題】有機溶剤と水とを含む混合液の受け入れまたは精製された有機溶剤の払出しを停止することなく、受入れる混合液または払い出す有機溶剤の品質を分析する。【解決手段】分析対象液を貯留可能な第１及び第２の容器１０１ａ，１０１ｂは分析対象液の供給ラインに切り替え可能に接続される。第１の容器１０１ａと共に分析対象液の循環経路を形成する第１の循環ラインと、第２の容器１０１ｂと共に分析対象液の循環経路を形成する第２の循環ラインとが切り替えされる。循環経路内の分析対象液は分析手段５０５，５０６，５０７によって分析される。第１の容器１０１ａと第２の容器１０１ｂの一方が供給ラインに接続される受入れ容器として、他方が循環経路を形成する分析容器として交互に切り替わるように、供給ラインと循環ライン形成手段が切り替えられる。【選択図】図２
