PROBLEM TO BE SOLVED: To provide a passage changeover type analyzer having flow rate fluctuation resistance and high stability and measurement accuracy even in the case of a minimum sample flow condition, and a measuring device using it. SOLUTION: This passage changeover type analyzer having a single sample cell part for measuring the concentration of a specific component in a sample by switching between a sample passage and a reference passage at a fixed period is characterized by providing an overflow line at least in either of the passages, and providing a member having a prescribed capacity in the overflow line. The passage changeover type analyzer having the single sample cell part for measuring the concentration of the specific component in the sample by switching between the sample passage and the reference passage at the fixed period is characterized by providing the member having the prescribed capacity at least in either of the passages. In this case, the analyzer is characterized by providing a suction means in the passage connected to the sample cell part. COPYRIGHT: (C)2005,JPO&NCIPI
