The present invention pertains to a chromatographic process for separating
saccharide monomers from dimers and/or saccharide trimers from dimers.
The separation is effected with a cation exchange resin. If saccharide
monomers are separated from saccharide dimers the cation exchange resin
has a high degree of crosslinking. If the saccharide dimers are separated
from saccharide trimers the cation exchange resins has a low degree of
crosslinking.
