Chromatograph is suitable for determination of the average molecular weight of polymers, their distribution, solution limiting viscosity, the size and conformation of macromolecules.

A chromatograph with 4 sensors (refractive index, light diffusion, viscosity and UV) fractionates macromolecules according to their hydrodynamic volume and allows the determination of molecular variables.
