Spatially Localized Voltage Control in Glass Microchannels for Enhanced Sample Handling Flexibility
Conference paper
Abstract
Electro-osmotically induced pumping (EOIP) can be used for sample and fluid handling in field-free regions in microfluidic devices. Here, EOIP for fluid handling in field-free regions is combined with electrophoretic separation, resulting in enhanced flexibility in sample handling. The influence of the EOIP-driven sample zone formation on the resulting peak area and separation efficiency was investigated. Increased EOIP voltages resulted in the injection of larger sample zones, as indicated by increased peak areas and decreased separation efficiency.
