Abstract

The invention discloses a thin-layer spectrum electrochemical detection device with a sandwich structure. According to the detection device, a rubber isolation pad, an upper-layer perspective window, a polymer gasket and a lower-layer perspective window are arranged between an upper-layer metal panel and a lower-layer metal panel in sequence; the polymer gasket is arranged between the upper-layer perspective window and the lower-layer perspective window to form a multilayered structure similar with a sandwich; a thin layer is internally provided with a working electrode, a reference electrode and an auxiliary electrode to form an electrochemical reaction tank of the three electrodes; a protective sleeve is arranged at the periphery of the lower-layer perspective window; a through hole is formed in the middle of the protective sleeve; the through holes can be used for just storing the lower-layer perspective window and the polymer gasket; electrode connecting inserting holes are formed in the outer side of the protective sleeve. The thin-layer spectrum electrochemical detection device with the sandwich structure has good air tightness; the thickness of the thin layer can be adjusted according to the polymer gasket so that excellent thin-layer electrochemical reaction characteristics are provided; the aim of in-situ spectrum detection of an electrochemical reaction product and an intermediate product can be realized.
