Measuring method and apparatus for measuring concentration of each component in the test solution used in the wet fluorescent magnetic particle examination

摘要

PROBLEM TO BE SOLVED: To provide a measurement method and measurement device of the component concentration of an inspection liquid to be used for a wet type fluorescent magnetic powder flaw detection test.;SOLUTION: The measurement method of the component concentration of an inspection liquid to be used for a wet type fluorescent magnetic powder flaw detection test is characterized by: introducing a stirred inspection liquid to a measurement tool 3; and, by using transmitted rays of light obtained by irradiating the inspection liquid from one side of the measurement tool 3 with the rays of light of an ultraviolet LED lamp 4a, visible light LED lamps 4b and 4c having multiple different wavelength and an infrared LED lamp 4d as a plurality of light sources having different wavelength and visible rays of light emitted via excitation, measuring each component concentration of the inspection liquid from the change of each of the detection values of an ultraviolet detector 5a, visible light detectors 5c and 5d and an infrared detector 5e which detect the transmitted rays of light and a fluorescent luminance detector 5b which detects the visible rays of light emitted via excitation and the detection value of each detector to be obtained in accordance with a difference in sedimentation characteristics accompanied by the time course of each component of the inspection liquid and the difference value of each of the detection values from the detectors 5c and 5e corresponding to the two light sources 4b and 4d having different wavelength among the light sources.;COPYRIGHT: (C)2013,JPO&INPIT
