Abstract


In order to get over disadvantages of existing electrochemiluminescent (ECL) cell, a novel micro-electrochemiluminescent (μ-ECL) cell based on flow injection was designed and fabricated. Made of indium tin oxides(ITO) and PDMS, it had solved the problems well and provided hardware for further study. In this paper, the design idea and plan of ECL cell were expound. Facture details were introduced and the structure of the cell was optimized. The cell has many advantages and innovations.In this paper, the ECL behavior of luminol on the ITO glass based on the flow cell was studied. The influences of main effect factors on the cell were studied and optimized. The performance and application of the cell were improved after optimization of main effect factors and structure of the cell.Application of the cell to real samples was studied on anti-oxygen ability evaluation of fruits. The ECL intensity of detection cell decreased linearly with the concentration of red grape. The anti-oxygen ability of red grape seed was stronger than red grape flesh. The cell has good reproducibility in real sample determination. Its design and function have satisfied the ECL analysis. It also can couple with other technologies,such as HPLC and CE et al. It will have a wide application in the real research and analysis.
