“…For the fractionation of oligo-and polysaccharides, adsorption chromatography on columns (51,132,759,760,764,1132,1208) continues to be the method of choice, with gradient elution (132, 759, 760) as a notable technical improvement, but gel filtration (324,832) offers some interesting possibilities of separation according to the degree of polymerization. There have only been two reports so far on the use of thinlayer chromatography for the resolution of monosaccharide mixtures (868,1119), and one on the use of dichromate-treated glass-fiber paper (528).…”
