METHOD AND APPARATUS FOR MEASURING EACH COMPONENT CONCENTRATION IN SUSPENSION TO BE USED FOR WET FLUORESCENT MAGNETIC PARTICLE FLAW DETECTION TEST

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for measuring each component concentration of a suspension to be used for a wet fluorescent magnetic particle flaw detection test in which the concentrations of a dispersant in the suspension and fluorescent magnetic particles can be simultaneously measured by a simple method and the concentrations can be instantaneously measured at high accuracy and the measurement accuracy and operability are improved.

SOLUTION: In the method and apparatus for measuring each component concentration of the suspension to be used for the wet fluorescent magnetic particle flaw detection test for detecting a flaw part by bringing the suspension obtained by mixing at least fluorescent magnetic particles into contact with the surface of a magnetized metal in a subject and collecting and sticking fluorescent magnetic particles to a flaw part on the surface, the concentration of the dispersant is measured by using transmitted light obtained by leading the suspension to a transparent measuring tool 3 and applying light of a light source 4 to the suspension from one side of the measuring tool 3 and excited and emitted visual light, based on a detection value of an ultraviolet detector 5 for detecting the transmitted light and a detection value of a fluorescent luminance detector 6 for detecting the excited and emitted visible light.
