universal calibration

in chromatography
A calibration of a @S05705@ set-up based on the finding that the retention volume of a molecular or particulate species is a single-valued function of an appropriate size parameter of this molecule or particle, irrespective of its chemical nature and structure. The product of the @I03140@ and molar mass, \([\eta]M\), has been widely used as the size parameter.
