Abstract
An electrophoresis apparatus for processing compounds in small sample volumes comprising a cathode in a static cathode buffer zone or compartment, an anode in a static anode buffer zone or compartment. The cathode disposed relative to the anode so as to be adapted to generate an electric field in an electric field area therebetween upon application of a voltage potential between the cathode and anode. A removable cartridge disposed in the electric field area between the anode and the cathode. The cartridge containing a first non-isoelectric separation barrier and also a second non-isoelectric separation barrier disposed between a selected one of the cathode buffer zone and the anode buffer zone and the first barrier so as to define a first chamber having an interstitial volume of less than 5 ml therebetween.
