title: [Theoretical study of contactless conductivity detector for electrophoresis chip].
abstract: Currently most electrophoresis chips use optical detection methods, which brings some difficulties in micromation and integration of electrophoresis chips. In order to solve this problem, a new high-frequency contactless conductivity detector for electrophoresis chip is designed. At the same time, theoretical study and analysis of this new detector are carried out, based on the construction of an equivalent circuit mode of high-frequency conductivity detector and the design of the structure. With the consideration of many factors including band broadening, the dimensions of the structure were designed and optimized. In summary, the detector has many advantages such as wide application range, simple structure and easy integration.
