Size-exclusion chromatography combined with online multi-angle light scattering (MALS) and refractometric (RI) detection has been employed for the molar mass characterisation of water-insoluble cationic methyl methacrylate-ethyl acrylate copolymers. The combined MALS/RI detection gives the opportunity to measure the absolute molar mass independent of recovery and retention. It is a favourable tool for tracing the changes in elution behaviour of the charged copolymer as the ionic strength is increased.
