Abstract:
1. A solution concentration distribution measuring device for measuring reaction distribution or concentration distribution of a material in a solution, comprising: a material detecting plate including: a flow passage forming part which forms a flow passage of the solution on the material detecting plate; means for stabilizing electric potential of the solution; means for irradiating a femtosecond laser from the semiconductor side to the flow passage side; means for making the femtosecond laser scan the material detecting plate two-dimensionally; means for measuring directly amplitude strength of a pulsed electromagnetic wave generated by irradiating the femtosecond laser to the material detecting plate with the means for the two-dimensional scanning; and means for measuring the material to be detected qualitatively and quantitatively based on the amplitude strength so as to obtain the reaction distribution or the concentration distribution of the material in the solution in the flow passage as a two-dimensional map, wherein the material-sensitive film constitutes a part of an inner wall of the flow passage, and the predetermined thickness of the semiconductor is optical infiltration length which is an inverse of optical absorption coefficient of the semiconductor.
