ABSTRACT:
A method of recording a densitogram representing densities of albumin, .alpha..sub.1 -globulin, .alpha..sub.2 -globulin, .beta.-globulin and .gamma.-globulin in an electrophoresis is disclosed. In order to display the densitogram representing the change in density of the substances, an area of the densitogram surrounded by a densitogram curve and a base line is made proportional to a total density T which is measured separately by a colorimetric method. Successive density signals X.sub.n are adjusted by multiplying them with a density output ratio R which is derived in accordance with the following equation, ##EQU1## wherein K is a coefficient denoting an area on a record paper per unit density, .SIGMA.X.sub.n is an accumulated density signal, Y is a gain of a recorder and P is a recording pitch of the recorder.
