1. An electrophoresis device comprising:
a flow passage with which a phoresis medium is filled;
a first electrode disposed at a cathode side of the flow passage;
a second electrode disposed at an anode side of the flow passage, wherein:
the flow passage includes a capillary and a block, with which a phoresis medium is filled;
the block includes a first flow passage for communication between the capillary and a phoresis medium container, and a second flow passage for communication between a buffer container which stores the second electrode and the capillary, and the first flow passage or the phoresis medium container includes a third electrode for abnormality confirmation;
a power supply for applying voltage across the first electrode and the second electrode, and the first electrode and the third electrode;
a pump for feeding the phoresis medium to the flow passage; and
a control section, wherein:
the control section executes control operations relating to an analysis workflow including a filling step of filling the flow passage with the phoresis medium, an electrophoresis step of executing electrophoresis of a sample, and an abnormality detection step of determining, based on a first current value and a second current value, a state of a current path which contains the phoresis medium filled in the flow passage, by applying voltage to the first electrode and the second electrode to obtain the first current value, and the first electrode and the third electrode to obtain the second current value, prior to the sample electrophoresis; and
the control section applies voltage to the current path for 20 seconds or longer in the abnormality detection step.
