Calibration curve in inverse size-exclusion chromatography (Ve/Vc - elution volume of the polymer divided by the volume of the column, log Mr - logarithm of (polystyrene) molar mass)

The inverse application of the size-exclusion chromatography (SEC) concept, inverse size-exclusion chromatography (ISEC) [1], utilizes a set of molecular probes with defined sizes to determine pore dimensions, and is also referred as chromatographic porosimetry [2]. ISEC provides an alternative to mercury porosimetry or nitrogen adsorption for the determination of the pore size dimensions and the surface area of [...]
