U12-E01. 3D cross-correlation dynamic light scattering (DLS) spectrometer

U12-E01. 3D cross-correlation dynamic light scattering (DLS) spectrometer

Description:
Photon Correlation Spectrometer (PCS) for dynamic (DLS) and static (SLS) light scattering measurements for angles in the 20-140º range and capacity of suppressing multiple scattering thanks to the 3D-cross correlation technology (down to 5% of transmission for sub-micrometer sample thickness). The instrument is equipped with a He-Ne laser and its software allows the estimation of particle size by Cumulant or CONTIN analysis. It is also possible to measure non-ergodic samples with a rotating sample holder.

Applications:
Determination of particle size and shape, size distribution, etc. in colloid systems (e.g. solid dispersions, micelles, microemulsions, nano-emulsions, polymers, vesicles or liposomes) Estimation of molecular weight of polymers and interaction parameters (e.g. second virial coefficient). Estimation of gel transitions.

U12-S01. Characterization of colloidal dispersions by Dynamic and Static Light Scattering (DLS and SLS) and Light Diffraction (Remote) OUTSTANDING

Determination of the size distribution of particles, droplets or micelles. Estimation of morphology, mass and aggregation number.

Available techniques include Dynamic Light Scattering (DLS),Static Light Scattering (SLS), and Light Diffraction (LD).  For DLS and SLS the samples must be in the form of a dispersion in water or other solvent.

For LD, dispersions and dry powders can be measured.
