Abstract
To facilitate fractionation of an electrophoretogram, the disclosed process differentiates signals representing the electrophoretogram so as to obtain the differential of the first order and to generate a first series of pulses representing changes of sign of the differential of the first order. The process differentiates again the differential of the first order so as to obtain the differential of the second order and generates a second series of pulses representing changes of sign of the differential of the second order. Output pulses are generated by logically processing the first and second series of pulses, whereby the electrophoretogram is fractionated on the basis of the timing of the output pulses.
