<p><P>PROBLEM TO BE SOLVED: To provide an impurity removal device capable of satisfactorily removing impurities of a gaseous body or a solid body which can be generated in a reaction tank from an optical probe, and a spectroscopic analyzer with the device. <P>SOLUTION: An impurity removal device 20 removes impurities of a gaseous body or a solid body from an optical probe 11 which is immersed in solution S to be stored in a reaction tank C, and includes: a tube 21 arranged toward the optical probe 11 in a state where one end 21a is immersed in the solution S in the reaction tank C; a pump 22 which is connected to the other end 21b to suck and discharge the solution S in the reaction tank C via the one end 21a; and a control part 23 which operates the pump 22 when a specific wave number component of a spectrum to be calculated from detection light via the optical probe 11 becomes smaller than a preset threshold. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
