The coating hapten was bound to the surface of microparticles through avitin biotin reaction. An electrochemical flow cell containing working electrodes and counter electrodes for initiation of the ECL reaction was constructed. Results showed that the detection limit for methsulfuron methyl was 0.1 ng/mL. [WT5HZ]展开更多
