Nano Particle Analyzer
HORIBA LB-550S
The LB-550S operates on the basis of dynamic light scattering. It allows for the precise measurement of nano particles in a size range from 1 nm to 6000 nm and a concentration range from ppm up to 40% solids. A very effective detector with a photomultiplier ensures the reliable measurement even of particles which scatter light only weakly such as proteins and polymers.
The analyzer is used for the measurement of fine suspensions, emulsions, all kinds of colloids and brines? in aqueous and organic media.
Application Examples
catalysts, ceramics, cosmetics, foodstuffs, inorganic materials, medical products, nano-coatings, paints, paper, pigment dispersions, plastics, polymer materials, research & development for nano-particles, semicondutors (CMP), ...

Function Principle
The focal point of the laser beam is brought as close as possible to the inner wall of the cell. This suppresses the effects of multiple scattering in highly concentrated samples and still provides sufficient signal strength for lower concentration samples because the scattered light is not attenuated by passing through a large volume of the sample dispersion. The angle of irradiation into the cell is also carefully controlled, eliminating the effects of stray and reflected light. This increases the signal-to-noise ratio and the ability of the LB-550 to measure diluted samples.Subject to technical modifications and errors
