Abstract

To realize the analysis with high precision in microfluidic chips

a detection system of electroosmotic flow（EOF） in microchannels based on virtual instrument is presented.Conventional methods to detect the EOF and its characteristics are introduced.The hardware structure of the detection system based on current-monitoring method is built up

and the human-machine interface is developed by the LabVIEW.Measurement of EOF on microfluidic chip is achieved.Experiment results demonstrate that the proposed system can satisfy the requirement of the detection of EOF in microchannel.
