A study of the capillary electrophoretic separations of proteins and peptides using high-molecular-mass polyethyleneimine (PEI) is presented. Experiments were performed in the PEI-coated capillaries together with the use of this polymer as a buffer additive under different separation conditions. The effects of pH and the concentration of PEI in the buffer on the electroosmotic flow and the migration...
The retention behaviour of water-soluble polymers and proteins in hollow-fibre flow field-flow fractionation was studied. For a charged polymer such as polystyrene sulphonate (PSS), a low ionic strength of the carrier solution can completely disturb the retention mechanism by overloading, resulting in early-eluting, deformed peaks. Overloading was observed at polymer concentrations far below the...
