Patent ID: 7419578

Claim:
A capillary electrophoresis apparatus, comprising: at least one capillary for filling a polymer; a polymer container being provided in a vicinity of a first end edge of said capillary; a polymer injector which injects said polymer into said polymer container and said capillary via said polymer container so that said polymer container and said capillary contain said polymer therein; a sample container being provided in a vicinity of a second end edge of said capillary; voltage applying means for applying voltage between said first end edge and said second end edge of said capillary; an irradiator for irradiating said capillary; fluorescence detection means for detecting fluorescence emitted from a sample via said polymer container; a first buffer solution cistern for holding a first buffer solution connected by a connecting portion to the polymer container; and a second buffer solution cistern for holding a second buffer disposed near the second end edge of the capillary; wherein the polymer container comprises a channel via which the polymer container, the capillary, and the connecting portion are connected, and wherein the voltage applying means applies voltage when the polymer is not substantially moved by a pressure difference between the first buffer solution and the second buffer solution.
