Recycle Gel Permeation Chromatography. Part I. Recycle Principle and Design. Part II. Analysis of Epoxy Resins.

Abstract

A new recycle circuit for Gel Permeation Chromatography (GPC), named alternate pumping (AP), is described and applied to the fractionation of epoxy resins. Conceptual as well as design details for AP recycle are presented. Advantages and limitations of AP recycle as compared with conventional recycle are discussed in detail. A calibration curve together with the molecular weight spectra of four competitive commercial epoxy resins are used to demonstrate that greatly improved resolution of oligomers into individual peaks is possible with recycle GPC.
