Abstract
The present invention includes: an optical fiber being provided either of between a light source and a measurement cell and between the measurement cell and a light detection part; and light path switching means adapted to achieve switching between a measurement cell passage state in which a light path formed by light transmission means passes through the measurement cell and a measurement cell non-passage state in which the light path formed by the light transmission means passes through a region different from the measurement cell, wherein calibration processing for a first calibration with a long calibration cycle is performed in the measurement cell passage state, and calibration processing for a second calibration with a short calibration cycle is performed in the measurement cell non-passage state.
