Abstract
Crescent distortion of output samples collected during a continuous free flow electrophoresis separation process is reduced by providing means with the electrophoresis chamber whereby lateral flow across the chamber may be controllably varied to introduce beneficial hydrodynamic compensation effects to minimize distortion of the sample streams within the electrophoresis chamber.
Claims3
In an apparatus for conducting a continuous free flow electrophoresis separation procedure, the apparatus comprising:
- a rectilinear buffer filled separation chamber defined by two elongate spaced apart parallel plates forming a front and a back to the chamber, two sides, an end comprising a collection manifold having a plurality of spaced apart collection tubes, an end comprising a buffer solution inlet manifold assembly;
- two buffer filled electrode chambers, each disposed adjacent to one of the sides of the separation chamber and separated therefrom by a porous membrane;
- at least one sample inlet port located at or near the inlet of the chamber;
- the improvement comprising means whereby flow within the apparatus may be controllably varied laterally across the chamber such that crescent distortion for at least one of a plurality of individual components of a sample introduced through the sample inlet port is minimized.
