Abstract

The densitometer comprises a reader (5) mobile relative to the electrophoretic trace, a device (24) for tracing the absorption curves and a device (39) for calculating the percentage or absolute values of each fraction of the electrophoretic trace. The tracing device (24) is a wire head printer, and the reader (5) and printer (24) are actuated by stepping motors via a microcomputer (3) consisting of microprocessors (CPU).
