Abstract
Preprocessing samples for nucleic acid analysis requires a means for effectively and accurately size-fractionating and dividing a nucleic acid sample in order to remove foreign substances that will negatively impact analysis performance. The present invention provides an electrophoretic collection device characterized by comprising: a collection hole for collection of a nucleic acid sample that has undergone electrophoretic separation; a light sourcethat radiates excitation light onto the nucleic acid sample; a detectorthat detects light that has been emitted from the sample due to the radiated light; and a dispensing mechanismthat collects a nucleic acid sample solution within the collection hole, wherein the light source, detector, and dispensing mechanism can access the collection hole from respectively different directions.
