Precise capillary electrophoretic interface for sample collection or analysis

摘要: A capillary electrophoretic system and method for accurate precise post-column manipulation of molecules separated by electrophoresis is disclosed. The the invention includes a separation capillary; detector positioned close to, preferably less than approximately one cm from outlet end sheath which surrounds directs collection buffer over end. With as described, correlation possible between detection components sample their emergence capillary. optical fibers connected to spectrophotometric method, such UV or fluorescence, including laser induced fluorescence. buffer, an reservoir, supplying inlet capillary, are in electrical contact circuit provide electric field required molecules. mixed with they emerge They then collected into on any device, vials, capillaries membranes, transferred other devices further analysis, mass spectroscopy.
