Abstract : In the first report gel filtration chromatography of three hemicelluloses in cadoxen solution, esparto xylan, birch xylan and pine glucomannan, were carried out on polacrylamide gel and on agarose gel. Molecular sieving of the hemicelluloses was obtained over the whole range of their molecular weight distribution on both gel types. Agarose gel was effective over a broader molecular weight range, which in particular included larger molecules and gave complete sieving for CMC-preparations, having DP-values up to 380. The second article reports the results from gel filtration of two rayon samples, having an average DP-value of 500 and 250, respectively. The difference between their DP-values is clearly reflected in the corresponding elution diagrams. (Author)
