Abstract

Using a microfabricated chip with a bed volume of 0.2 µL we demonstrate the validity of the scaling laws for molecular mass transport of isoelectric focusing (IEF) in free flow. Nano- or microlitre sample volumes can be concentrated within 430 ms by a factor of up to 400. These very fast performances make the chip applicable to proteomic analysis and for continuous monitoring of biochemical processes.
