ABSTRACT:
After a sensor section has been dipped in a liquid sample, the sensor section is moved into a predetermined atmosphere, which is substantially free from occurrence of absorption or scattering of exciting light and fluorescence. In the state, in which the sensor section has been located in the predetermined atmosphere, exciting light is produced by a light source and is propagated through the interior of the sensor section. The exciting light is radiated out from an outside surface of the sensor section in order to excite a fluorescent substance for indicating the presence of a substance to be analyzed in the liquid sample. Fluorescence, which is produced by the fluorescent substance when the fluorescent substance is excited by the exciting light, is detected by a photodetector.
