Abstract
The present invention relates to an apparatus and method for the separation and purification of charged and neutral compounds in an analyte solution by electrophoretic means using a plurality of compartments (1) to contain the analyte solution, an chemical buffering system (2) to fix a pH value or a pH gradient in its portion(s) contacting the analyte solution and an electrical field imposed by electrical means (4) disposed in at least two of said compartments. This invention allows one to differentially separate charged and neutral compounds, to extract the migrating compounds from the chemical buffering system (2), to recover the purified compounds mainly in solution and to collect them in the various compartments (4), preferably at various pI.
