Abstract
To achieve efficient electrophoresis, after the last run is ended and before pre-run is performed, in a state where the electrophoresis medium used in the last run remains within a capillary, and two ends of the capillary are immersed in an electrophoresis buffer solution, whether a current value, which is based on a potential difference generated between the two ends of the capillary by applying a voltage by a high-voltage power supply to at least one of the electrophoresis buffer solutions on cathode and anode sides, is equal to or smaller than a first value is detected, and when the current value is equal to or smaller than the first value, an output section outputs a warning.
