    Abstract: In a microfluidic system (partially shown by element 178 in the figure and elements thereupon) using electrokinetic forces, the present invention uses electrical current or electrical parameters, other than voltage, to control the movement of fluids through the channels of the system. Time-multiplexed power supplies (200 and 202) also provide further control over fluid movement by varying the voltage on an electrode connected to a fluid reservoir of the microfluidic system, by varying the duty cycle during which the voltage is applied to the electrode, or by a combination of both. A time-multiplexed power supply can also be connected to more than one electrode for a saving in cost.

    Abstract: The present invention provides a microfluidic system (100) 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 (110) in the microfluidic system are received by the photodetector (130). The intensity of light received by the photodetector is modulated by the movement of species bands (123) through the channel under electrophoretic forces. By Fourier analysis, the velocity of each species band (123) is determined and the identification of the species is made by its electrophoretic mobility in the channel (110).
