The Gold-Standard in Light Scattering
Light scattering instruments based on goniometers have been the backbone of advanced research in the field of colloids and polymers for many years. A light scattering goniometer is a form of multi-angle light scattering instrument (MALS), which is characterized by the fact that a very large angular range can be measured with a rotatable arm and thus a very high precision can be achieved in DLS and SLS measurements.
With the LS Spectrometer™ II, LS Instruments combines the advantages of this technology with the ease of use of DLS instruments. The LS Spectrometer™ II can be used for the measurement of:
» Particle size & polydispersity
» Particle shape
» Molecular weight
» Sample structure & particle interactions
» Viscosity
