✦ Synopsis

after correction of instrumental spreading, w(uo) can be expressed by the integral equation

The relationship between the experimental function E(u) for the viscosity and the chromatogram

where uo is the elution volume under the integral sign and D(U,UO) is a function that describes the shape of the band spreading curve of a monodisperse sample. The relationship between the experimental chromatogram e(u) is given by the Tung equation. If the function D(U,UO) is independent of the molecular weight, then it is possible to solve these equations simultaneously and to calculate the functions w(uo) and D(u, UO). A mathematical method is given.
