説明
The relation between column efficiency and molecular weight of a polymer sample in gel permeation chromatography was studied.<BR>Usually, a column efficiency in the number of theoretical plates per foot is measured from a chromatogram of organic solvents, such as acetone and benzene, This method has a disadvantage that it is unsuitable for estimating undesirable broadening of chromatograms of a high molecular weight sample.<BR>From our experiments with reverse flow technique, the following approximate relation of the height equivalent to the theoretical plate, H, and molecular weight of the sample, M, was obtained.<BR>logH=A+BlogM<BR>In this relation, the information about undesirable broadening of chromatograms in the high molecular weight region in GPC was given.<BR>The reverse flow technique is a useful one in GPC to obtain a column efficiency at high molecular weight region. The application of this technique is also described in this report.
