Electrophoretic electrode, method of/and system for capillary electrophoresis using the electrophoretic electrode and fraction collector assembled into the capillary electrophoresis system

摘要

The electrophoretic electrode has two capillaries (2, 3) possessing different diameters and which are coaxially telescopically disposed to form a gap (14) having a predetermined width dimension between them, electrophoresis being caused in the gap 14. The electrode has an intermediate fractured portion, which is covered by a cover material, i.e., polyacrylamide gel containing an electrolytic buffer solution to form an electrically connected portion 8. The electrode may be used for electrophoresis to separate a large quantity of electrophoretically purified substance continuously and quickly.
