Multi-angle dynamic light scattering (DLS)

In addition to conventional light scattering equipment operating at a single angle, Softmat is the only laboratory in Toulouse to be equipped with multi-angle light scattering equipment (SLS and DLS), enabling polymer or colloidal solutions to be characterised as effectively as possible.

Equipment features

LS instruments:
  • particles size range: 0.15 nm to 5 microns
  • measurement angles: 12° to 150°
  • laser at 660 nm
  • temperature : up to 90°C
  • DLS depolarisation for anisotropic particles
  • 3D cross-correlation for concentrated solutions
