Portable, wireless capillary electrophoresis - capacitance-to-digital based contactless conductivity detection system

Abstract

Capillary electrophoresis is considered as promising analytical technique in environmental analysis. Unfortunately, capillary electrophoresis provide inconsistent and imprecise data in changing environment analysis. The imprecision is mainly caused by the fluctuations of temperature. Numerous commercial devices have temperature regulation implemented, which, due to large size and energetically inefficient operation, completely restricts field portable, autonomous and environmental applications. In this work design of semi-automated, wireless capillary electrophoresis coupled with capacitance-to-digital based contactless conductivity detection system is described. This research work provides algorithms and methods that compensate thermal fluctuations showing convenient way of obtaining precise and robust data in changing environment. Further details and issues will be presented and discussed in the conference.
