Recycle Gel Permeation Chromatography III Design Modifications and Some Results with Polycarbonate.

Abstract

In previous communications a new recycle device for Gel Permeation Chromatography (GPC) was described and its advantages demonstrated with an analysis of epoxy resins. This device uses a principle which was termed alternate pumping (AP). In the present communication, a modified design for AP recycle is described and some results with a polycarbonate resin are analyzed. This new design differs from the previous one in two major features. It utilizes only one 6-port switching valve and it excludes the refractometer cell from the recycle loop. These features simplify the recycle system and eliminate the problems that were caused by subjecting the refractometer cell to high pressures. (Author)
