ELECTRONIC INTEGRATED MULTI-ELECTRODE DETECTION SYSTEM BASED ON POTENTIAL MEASUREMENT

The present invention discloses an electronic integrated multi-electrode detection system of a potential determination. The detection system comprises a multi-electrode array (10), a circuit unit (20) and a total signal output and acquisition unit (30). The circuit unit mainly comprises a multi-electrode array signal input end (21), a high input impedance voltage follower (22), a phase shifting filter circuit (23), an extension module input end (24), a summing circuit (25) and a total output signal end (26). The detection system disclosed by the present invention can obviously promote 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. The electronic integrated multi-electrode detection system of the potential determination of the present invention is applicable to all universal multi-electrode detection systems of potential determinations.
