It allows rapid measurements even at high concentrations and offers accurate particle sizing over a dynamic range of 0.1 to 2000 microns, using just two lens systems.Īt ATA Scientific we sell innovative instruments from leading manufacturers in the particle, surface, life and material sciences. The Malvern Spraytec laser diffraction system provides real-time particle size distribution of sprays and aerosols. Analysis and instrument control is via simple, intuitive browser-style software. These deliver precise, high resolution wet and dry measurements with better than 1% accuracy and reproducibility. These include the Mastersizer 30E from Malvern Panalytical. This technique is capable of measuring particles from 10nm to 3500 microns.ĪTA Scientific supplies a range of particle sizing instruments that employ laser diffraction technology. These scattering patterns are measured by the detectors and particle size distribution is determined from the resulting data. Larger particles bring about a high intensity of scattering at low angles to the beam, smaller particles create a low intensity signal at much wider angles. The laser light is scattered in a variety of angles. The particles are dispersed in a liquid (often water) or air and illuminated by a collimated laser beam. This means it provides a result for the whole sample rather than for individual particles. Laser diffraction is an ensemble technique of particle sizing. It is a rapid, highly reproducible measuring technique which provides particle size distribution over a wide particle diameter range. Laser diffraction, also known as Low Angle Laser Light Scattering (LALLS), is widely used for particle size analysis and is the standard method in many industries.
