Claims

[Claims for Utility Model Registration] One end surface serves as a vertical channel bed in a cell channel chamber of an electrochemical detector, and the other surface forms a substantially vertical channel bed located above the inlet channel. An outlet channel, a reference electrode insertion hole and a counter electrode insertion hole communicating with the outlet channel are bored, and the one end surface has a small hole that becomes the end of the inlet channel, and a small hole located above the small hole. Corresponding to the counter electrode insertion hole,
and a cell block formed by opening a horizontal slit serving as the starting point of the outlet flow path; and a cell flow path chamber having one end surface of the cell block as a vertical flow path bed, for defining a basin area including the small hole and the horizontal slit. a gasket having an opening, and an electrode surface that is pressed into contact with the gasket from the opposite side of the cell block and that creates a potential difference with the counter electrode on a surface surrounding the cell flow path chamber corresponding to the opening of the gasket. 1. An electrochemical detector comprising: a working electrode; and a clamp mechanism for pressing the back surface of the working electrode to maintain a cell structure of the detector comprising the cell block, gasket, and working electrode.
