Claim 0:
1. A method to control an electrophoresis device, comprising:
introducing a polymer not including a fluorescent dye into an electrophoresis flow channel after at least one electrophoresis using the fluorescent dye such that the polymer fills the electrophoresis flow channel;
introducing, into the electrophoresis flow channel filled with the polymer, a sample including a component into which the at least one electrophoresis causes the fluorescent dye to be inserted;
applying a voltage to the electrophoresis flow channel filled with the polymer and the sample such that the fluorescent dye accumulated in the electrophoresis flow channel from the at least one electrophoresis using the fluorescent dye is inserted into the component in the sample;
detecting fluorescence from the sample electrophoresed by the applying of the voltage to the electrophoresis flow channel filled with the polymer and the sample;
comparing an amount of the fluorescence detected with a threshold value set to determine that the fluorescent dye is removed from the electrophoresis flow channel sufficiently for an analysis mode;
filling the electrophoresis flow channel with a polymer including the fluorescent dye after the amount of the fluorescence becomes smaller than the threshold value;
introducing a sample for an analysis into the electrophoresis flow channel filled with the polymer including the fluorescent dye;
applying a voltage to the electrophoresis flow channel filled with the sample for the analysis and the polymer including the fluorescent dye such that the sample for the analysis is electrophoresed in the electrophoresis flow channel and a component in the sample for the analysis is separated; and
detecting the component in the sample for the analysis marked by the fluorescent dye,
wherein the introducing of the polymer not including the fluorescent dye, the introducing of the sample, and the applying of the voltage to the electrophoresis flow channel filled with the polymer not including the fluorescent dye and the sample are repeated until the amount of the fluorescence is determined to be smaller than the threshold value.
