  • Patent number: 11486908
    Abstract: An electronic integrated multi-electrode detection system of a potential determination includes a multi-electrode array, a circuit unit and a total signal output and acquisition unit. The circuit unit includes a multi-electrode array signal input end, a high input impedance voltage follower, a phase shifting filter circuit, an extension module input end, a summing circuit and a total output signal end. The detection system promotes the detection sensitivity and increase the accuracy and precision of detection results. The detection system can be used for monitoring the change in trace ion concentration in a sample, analyzing a constant conventional sample and analyzing a sample with higher error requirement. The detection system can be widely applied to various analysis detection fields, including life sciences, environmental sciences, medicine clinics, and the like.
