Abstract

The present invention provides an electrophoresis device with improved abnormality detection capability. The electrophoresis device according to the present invention includes a flow passage with which a phoresis medium is filled, a first and second electrodes disposed at respectively a cathode side and an anode side of the flow passage, a power supply for applying voltage across the first and second electrodes, a pump for feeding the phoresis medium to the flow passage, and a control section. The control section executes operations including filling the flow passage with the phoresis medium, executing electrophoresis of a sample, and applying voltage to the first and second electrodes prior to the sample electrophoresis to determine a state of a current path based on a value of current flowing through the current path. The control section applies voltage to the current path for 20 seconds or longer in the determine step.
