description PURPOSE:To raise sensitivity, responsiveness and analysis accuracy in a micro- flow cell type voltammetry detector by making an upper block that opposes working electrodes an electricity conductive electrode with opposite polarity. CONSTITUTION:The main body 1 of a detector has a three-layer construction which consists of a upper block 2, space 3 and lower block 4. Because the upper block 2 is also used as an electrode with opposite polarity, it is constituted with a material that is electricity conductive and has rigidity, and the spacer 3 is made of an insulating material and used for forming a long and slender flow channel 5 between the upper and lower blocks. In the lower block 4 working electrodes 11-20 are embedded, and the upper faces of the individual working electrodes are exposed to the flow channel 5 at the upper face of the lower block 4. The electric currents that flow between the block 2 and working electrodes 11-20 in the liquid that is to be tested and introduced from a liquid intake tube 6 to the flow channel 5 are detected to analyse the liquid.
