Determination system and method of the molecular weight and intrinsic viscosity of the polymer distribution using gel permeation chromatography

摘要

(57) Abstract It is the system which analyzes the data from of the gel transmitted chromatography (GPC) and the size steric exclusion chromatography (SEC) system which decides the molecular weight distribution (MWD) of method or the polymer sample and intrinsic viscosity law (IVL). With the smallest square minimization conformity it can use the data from the detector of two or more. New method includes the simultaneous decision of MWD and IVL of the sample which uses the data from the detector of two or more. The detector, the light scattering (LS) detector, includes viscosimeter (v) and the refractive index (RI) detector. As for this invention, it does not respond to the detector noise in the base line territory of peak curved line.
