Abstract

A microfluidic device with integrated temperature control for the electrophoretic separation and conduction of immunoassays is introduced. The separation channel is actively cooled with the use of a thermoelectric cooler (TEC) embedded into the microfluidic housing manifold. The introduction of the cooling also allowed for the utilization of shorter separation distances with higher separation voltages with effective dissipation of Joule heating. The optimization effects were evaluated with a kinetic CE method known as non-equilibrium capillary electrophoresis of non-equilibrium mixture (NECEEM). This method of active cooling will be applicable to other microfluidic affinity separation systems.
