【Abstract】 The use of multiple detectors in GPC/SEC technique is gaining more and more attention in both academic and industrial fields in recent yesrs. This paper gives some important principles on the different detector combinations in GPC/SEC techniques, especially on the four-capillary bridge design differential viscometer(DV) and right angle laser light scattering(RALLS) of Viscotek’s, and shows that the multiple detector GPC/SEC is a useful tool for studying polymer morphologies, properties of polymer solution and the relationship between polymer structure and its properties.更多还原
