Abstract: A microfludic system with a non-enzymatic sensor system by an electroosmotic flow control is provided to quantitatively analyze an analyzing material such as glucose without fixing any enzyme. A microfludic system(1) with a non-enzymatic sensor system by an electroosmotic flow control includes a first substrate(10a) and a second substrate(10b). The first substrate a microfludic channel network(110), first to fourth storage tanks(121,122,123,124), a first chamber(131), and a second chamber(132). The second substrate includes a plurality of metal thin films(140a~140h) and an electrode assembly(150) for electro-chemically analyzing sample solution. The electrode assembly comprises an operational electrode, a reference electrode, and a relative electrode. The operational electrode and the reference electrode are in contact with the first chamber and the relative electrode is in contact with the second chamber. The second storage tank and the third storage tank are connected to the microfludic channel network between the first storage tank and the first chamber by being deviated from a traveling path of the microfludic channel network.
