Delsa Nano HC Particle Analyzer

This system measures the diameter and surface charge of particles in solution. The characterization range for diameter is 0.6 nm to 7 µm, and zeta potential of particles in the size range of 0.6 nm to 30 μm. Dynamic light scattering (DLS) uses a laser source to scatter light from particles in a suspension. The fluctuations in light intensity is correlated to particle diameter using photon correlation spectroscopy. Electrophoretic light scattering is used to measure the zeta potential of particles in solution.

The theory of operation may be found in the Introduction of the document here.
