Notes:
The automation of a microelectrophoresis apparatus is described. It relies on digital techniques for the electric field generation, the conductance measurement, the cuvette positioning, and the temperature rise estimation deduced from the conductance. A current source is used with programmable shape, frequency, duty cycle, and duration. All the measurement steps are successively controlled by the microprocessor. As described herein, the particles motion is recorded with a camera. The apparatus is built from independent (software and hardware) modules and other detecting devices could easily be adapted.
