- Abstract:
- The problem of quantitation in size-exclusion chromatography (SEC) of polymers and oligomers is discussed, and a strategy for finding an appropriate combination of detectors and mobile phases for a given type of copolymer is described. This approach comprises the determination of response factors of different detectors for each homopolymer, and a simulation of dual detector SEC. The reliability of results is evaluated by analysis of homopolymers, polymer mixtures and copolymers of methyl methacrylate, ethylene oxide and dimethyl siloxane. Monodisperse fatty alcohol ethoxylates are used as models for block copolymers. (C) 1997 Elsevier Science B.V.
