摘要： PURPOSE:To eliminate the staying of an eluted measurement interfering component caused at the time of stopping pure water, and prevent lowering of purifying function by forming a circulating line passed through an ion exchange pure water generator, and supplying the pure water extracted from this line to a far ultraviolet ray absorbance meter as zero water. CONSTITUTION:A circulating line in which one end is connected to the discharge hole 10a of an original water tank 10, and the other end reaches the water receiving hole 10b of the tank 10 through an ion exchange pure water generator 1 is formed. In this line 12, a branched line 12 branched on the lower stream side of a 5-mum filter 15 and connected to a wash water inlet port 4a communicating with the wash water tank of a far ultraviolet ray absorptiometer from a branching point B is formed. Since the tap water introduced into the tank 10 is discharged by a pump 13 after operation is started, purified by the generator 1, and then refluxed again to the tank 10, the purity of the raw water in the tank 10 is increased. Thus, since the purity of the water introduced into the generator 1 is also enhanced, the reduction in purifying function of the generator 1 is prevented to extend the life, and economic property is improved.
