Description
The LA960 laser scattering particle size distribution analyser instrument consists of two light sources, a sample handling system to control the interaction of particles and incident light, and an array of high quality photodiodes to detect the scattered light over a wide range of angles. The scattered light collected on the detectors is used to calculate the particle size distribution of the sample analysed using Mie Theory. Suitable for suspensions, emulsions, powders, pastes, gels, and cream.
Uses / Applications
Particle size distribution, colloid / emulsion studies, nanoparticle formation / characterisation
