IPC: G01N37/00
Filed: 2001-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a dilution method for solution and dilution device for solution facilitating the dilution of a solution. SOLUTION: A solution segment formed by being introduced from a solution inlet capillary 3 and parted in a part IC located between the solution inlet capillary 3 and a solution discharge capillary 4 in a main capillary 1 is sent to the downstream side of the main stream capillary 1 by a buffer solution formed as electroosmosis flow by applying a prescribed voltage to both ends of the main capillary 1. The solution segment is partially branched to a branch capillary 2, and the remainder flows in the main capillary 1. Since the solution segment carried in the branch capillary 2 reaches a combined point 2B with a prescribed time lug, it is never combined with the solution segment carried in the main capillary 1. As a result, the first solution segment is parted into two and consequently diluted.
