- 中文摘要: A model for the Gel permeation chromatographic separation of a polymer and a new calibration method have been developed, based on the exclusion of the polymer from the pores of the packing material. We propose that the calibration curve a plot of log(1-.sqroot.(K)) versus log (molecular weight), where K is the elution volume coefficient, is close to linear over a K range of 0.15-0.85. We compare our procedure with that of Haller for various sets of data. Our procedure is generally better with lower standard deviations. When extrapolated, it gives a critical permeation size characteristic of the glass column packings.
