PROBLEM TO BE SOLVED: To provide a water quality analyzer constituted to positively wash a sampling system in a short time by simplifying the constitution of the sampling system. SOLUTION: In this water quality analyzer, sample water S metered in a sample water metering part 1, and dilution water D metered in a dilution water metering part 2, are mixed to obtain sample liquid SL. The sample liquid SL is supplied to a combustion reaction part 9 through a sample liquid metering part 6, and gas generated in the combustion reaction part 9 is analyzed by a gas analyzing part 11 to analyze a specific component contained in the sample water S. In order to mix the sample water S and dilution water D, the liquid outlet side of the dilution water metering part 2 is connected to the liquid inlet side of the sample water metering part 1, and bubbling air BA is supplied to the sample water metering part 1.
