Study on Equivalent Circuitry Model of Cell for Capacitively Coupled Contactless Conductivity Detection

摘要：

A parted extended model for the detection cell consisting of a network of resistors and capacitors was given in this paper, taking into account the effects of the spatial component of the solution conductivity as the electrophoretic zones pass inside the detector. The parted model, was compared to the simple model, and some results were obtained. The parted extended model can explain the overshooting phenomena and current distributing at the electrode, which can not explained by simple model. The parted extended model more accords with the structure of cell.
