Title: Electrophoresis device
Inventor: CHIBA TAKASHI
IPC: G01N37/00
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To make component analyzable and qualitative analysis performable by an electrophoresis device constituted so as not to be influenced by the position of a tank or the inner liquid level by providing a fluid resistance moderating movement of liquid due to the head difference of electrolytic solution between an electrolytic solution tank and a separation column. SOLUTION: At actual measurement, a voltage is impressed between electrolytic solution injection holes 11c-12 under the condition in which grooves 13a, 13b are filled with the electrolyte solution to let sample liquid flow from the hole 12 side to the hole 11c side, and the sample liquid is in the condition of traversing the groove 13a. Next when voltage is impressed so as to let flow the liquid to the injection hole 11a to 11b, the electrolyte solution taking in the sample liquid flows to the electrolytic solution tank 11b side, and a plurality of portions of the sample liquid are separated from each other by difference of the moved time. A detector identifies the separated components, and the percentage content can be measured by signal strength.  In this way because fluid resistance modulting movement of electrolytic solution due to the head difference of electrolytic solution is provided between the solution tank and a separation column, an electrophoresis device of simple constitution can be realized without being influenced from the position and the liquid level of the electrolyte solution tank, and the concentration and the quality of components can be analysed.
