The present invention provides a microfluidic system for fast, accurate and low cost electrophoretic analysis of materials in the fields of chemistry, biochemistry, biotechnology, molecular biology and numerous other fields. Light from periodically spaced regions along a channel in the microfluidic system are received by a photodetector. The intensity of light received by the photodetector is modulated by the movement of species bands through the channel under electrophoretic forces. By Fourier analysis, the velocity of each species band is determined and the identification of the species is made by its electrophoretic mobility in the channel.

[ What is claimed is:] [1.] A method of performing high-speed electrophoretic analysis of subject materials, said method comprising:holding said subject materials in solution in a channel of a microfluidic system;subjecting said materials to an electric field so that said subject materials move through said channel and separate into species bands;directing light toward said channel at periodically spaced regions along said channel simultaneously;receiving light from said channel; andanalyzing frequencies of light intensity of said received light so that velocities of said bands along said channel can be determined for analysis of said materials.
