Capillary bed electrophoresis

A capillary bed electrophoresis device for separating and collecting large-scale electrophoretic samples is disclosed. The invention relates to an improvement in the anticonvective packing and cooling system comprising a series of capillaries through which the sample and an eluent are driven by force. The sample is separated via an electrical gradient established axially within the capillaries while a coolant may be circulated intimately around the exterior of said capillaries to remove any Joule heating. The separated components are then collected at the discharge end of the capillaries. The system may be used with either continuous or batch electrophoresis devices.
