MEASURING DEVICE, PROBE FOR MEASURING DEVICE, AND MEASURING METHOD OF SOLUTE CONCENTRATION AND/OR FLOW RATE OF LIQUID IN PASSAGE

摘要

PROBLEM TO BE SOLVED: To provide a measuring device and a probe for the measuring device capable of improving operability by enabling a measuring position to be easily changed, and a measuring method of the solute concentration and/or the flow rate of liquid in a passage.;SOLUTION: This measuring device 1 is equipped with a light source module 100, and a probe 50 dipped in a sample solution in the passage 20, for condensing and irradiating excitation light and probe light to the sample solution. The probe 50 is equipped with an optical fiber 103 for guiding the excitation light and the probe light, a condensing lens 40 for condensing the guided excitation light and probe light, and a mirror 41 arranged in parallel so as to be faced to the bottom surface of the condensing lens 40. The excitation light condensed and irradiated to the sample solution forms a thermal lens in the sample solution, and the probe light transmitted through the thermal lens is reflected by the mirror 41, and a detector 54 detects the reflected probe light.;COPYRIGHT: (C)2005,JPO&NCIPI
