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
