摘要：
A system and method for analyzing data from a gel permeation chromatography (GPC) or size exclusion chromatography (SEC) system for determining a polymeric sample's molecular weight distribution (MWD) and intrinsic viscosity law (IVL). Data from two or more detectors is used with a least-squares minimization fit. A novel method includes the simultaneous determination of a sample's MWD and IVL using data from two or more detectors. Detectors include a Light Scattering (LS) detector, viscometer (V) and a refractive index (RI) detector. The present invention is insensitive to detector noise in the baseline regions of the peak curve.
