WebGel Permeation Chromatography, GPC, is a form of chromatography that is based on separation by molecular size rather than chemical properties. GPC or Size exclusion chromatography, SEC, is widely used for molecular weight and molecular weight distribution, MWD, determination. In itself, SEC does not give an absolute molecular weight and must … WebJul 19, 2011 · In general, the higher the boiling point of a liquid, the higher its retention time. So we would expect the ethanol to “come off the column” the first and then the 1-propanol; the ethanol would have a shorter retention time than the 1-propanol. This would be recorded as a two peaks.
