Solution concentration distribution measuring device

Detailed Technology Description

[PROBLEMS] To providea device for detecting a reaction distribution or a concentration distributionof a material present within amicroflow passage for a solution chemicalreaction. [MEANS FOR SOLVING PROBLEMS] A material distributionmeasuring device (1) for measuringa reaction distribution or a concentrationdistribution of a material contained in a solution. The material distributionmeasuring device (1)comprises a materialdetecting plate (5) comprising a material-sensitive film(21) provided on an insulator (22) providedon a semiconductor (23), a flowpassage forming part (6) forming asolution flow passage (12) on the materialdetecting plate (5), means for stabilizingthe potential of the solution, means for applying a pulsed laser beam (9)from the semiconductor (23) side tothe flow passage (12) side, means forscanning the material detecting plate(5) two-dimensionally with use of the pulsed laser beam (9), means formeasuring the amplitude strength of pulsed electromagnetic waves generated uponthe application of the pulsed laser beam (9) to the material detecting plate(5), and means for obtaining a reaction distribution or a concentrationdistribution of the material contained in the solution within the flow passageby qualitatively measuring the material to be detected from the amplitudestrength. The material-sensitive film (21) constitutes a part of the inner wallsurface of the flow passage (12).
