【 摘 要 】

The present workdescribes a low-cost electrochemical "wall-jet" detector for flow analysis.The electrolytic solution enters into the cell through a tube of stainless steel(200 to 300 µm i.d), reaching to the center of the working electrode perpendicularlyand then being mixed to the remaining solution in the cell, which flows underatmospheric pressure into a waste reservoir. The proposed electrochemical detectorcan be used with any type of working electrode, from commercial to home-made,such as glassy carbon and metallic electrodes (modified or unmodified), whichenlarge the applications of the electrochemical detector.
