Abstract:
1. An electrophoresis apparatus for separating analytes in a sample, comprising: an electrophoresis chamber comprising a cathode, an anode and a housing; a separation chamber having an average inner cross-section of at least 1000 micrometers and positioned within the housing and comprising an inlet end, an outlet end, and one or more cooling capillaries in the form of tubes positioned inside the separation chamber such that the longitudinal axis of at least one of the cooling capillaries is parallel to the direction of electric current flow from the anode to the cathode, wherein the ends of the cooling capillaries are adapted to be coupled to a cooling device that allows cooling medium to pass through the cooling capillary; and a cooling device coupled to either one or both ends of the cooling capillary or capillaries through a connector having a mechanic strength tolerable to a pressure of at least 10 psi.
