Abstract
A microfluidic device (11) is provided for separation and analysis of microfluidic samples. The device comprises: a separation channel (10); a first electrolyte channel (12) configured to provide a flow of high conductivity electrolyte solution, in use; and provided with a positive electrode (13) at a downstream outlet of the channel; a second electrolyte channel (14) configured to provide a flow of high conductivity electrolyte solution, in use, and provided with a negative electrode (15) at a downstream outlet of the channel; and wherein the flow of electrolyte through the first and second electrolyte channels removes electrophoresis products and gas bubbles from the device; and wherein the presence of the electrolyte provides a substantially homogenous electric field across the separation channel.
