Abstract: PURPOSE:To identify a sample accuracy with a correct PU value by recognizing as potential gradient value of a terminal ion the first of potential gradient values whose ion component zone length is larger than the reference length. CONSTITUTION:A potential gradient detector of an equispeed electrophoresis analyzer 2 outputs a signal beta to a data processor 3, which detects potential gradient values and zone lengths of individual ion component zones and at the same time, regarding the ion components contained in signals which will be inputted after the value of the signal beta exceeds a threshold V, the zone length thereof is compared with a preset reference length T0. When the zone length of the ion component zone is smaller than the reference length T0, the subsequent ion component follows the same procedure. This operation is repeated to select the potential gradient closest to threshold V with the zone length larger than the reference length T0. Thereafter, the device 3 recognizes the selected potential gradient as potential gradient of the terminal ion to determine PU values of ion components which are outputted to a plotter 4.
