The LS Spectrometer™ II is a goniometer-based variable-angle light scattering instrument for Static Light Scattering (SLS) and Dynamic Light Scattering (DLS). It offers the most comprehensive nanoparticle characterization and can be further enhanced with various options, such as Modulated 3D technology for measuring turbid samples.
Light scattering instruments based on goniometers have long been the cornerstone of advanced research in colloids and polymers. A light scattering goniometer is a type of multi-angle light scattering (MALS) instrument, characterized by its ability to measure a wide angular range using a rotating arm, enabling extremely high precision in DLS and SLS measurements.
With the LS Spectrometer™ II, LS Instruments combines the advantages of this technology with the ease of use typical of DLS instruments. The LS Spectrometer™ II can be used to measure:
✔ Particle size & polydispersity
✔ Particle shape
✔ Molecular weight
✔ Sample structure & particle interactions
✔ Viscosity
