<p>The purpose of the present invention is to improve user convenience in use by classifying the correction of radiation change by an optical fiber and the correction of radiation change by a measurement cell. An optical analyzer comprises: an optical fiber (51(52)) which is arranged at least one among a gap between a light source (3) and a measurement cell (2) and a gap between the measurement cell (2) and an optical detector (4); an optical path switching means (6) which switches between a measurement cell passing condition (P) in which an optical path (L) formed by an optical transmission means (5) passes the measurement cell (2), and a measurement cell non-passing condition (Q) in which the optical path (L) formed the optical transmission means (5) passes a region different from the measurement cell (2) and performs a correction process for a first correction having a long correction period in the measurement cell passing condition (P) and a correction process for a second correction with a short correction period in the measurement cell non-passing condition (Q).</p> |
