PS&HC - Polysaccharides & Hydrocolloids

Begin of page section: Contents:

Analysis and characterization of polymers and hydrocolloidal systems whith particula emphasis on polysaccharides.

Experimental

Analytical Separation Techiques (SEC, AF4) with subsequent in-line detection

  • SEC - mass / scattering intensity / intrinsic viscosity
  • AF4 - mass / scattering intensity

to obtain distributions and mean values

  • molar mass (degree of polymerization), Mw, Mn
  • excluded volume (Ve), sphere equivalent radii (Re)
  • translational diffusion coefficients (DT)
  • packing density (rho_e), preferences for interaction (A2, SMH K)

Viscosity & Rheology of homogeneous an dheterogeneous aqueous systems

  • shear dependent behaviour of polymer solutions or colloidal dispersions
  • viscoelastic profiling
  • stabilty testing upon controlled stress

Surface and Interface qualities of hydrocolloidal systems

  • surface / interface tension, contact angle
  • adsorption behaviour
