Instrument: Malvern Mastersizer 3000/3000E laser diffraction particle size analyzer

The Malvern Mastersizer 3000/3000E is a laser diffraction particle size analyzer available for both dry and wet dispersions of particles from nanometer to millimeter ranges. A laser beam passes through a dispersed particulate sample and the angular variation in intensity of the scattered light is measured. The angular scattering intensity data is then analyzed to calculate the size of the particles that created the scattering pattern using the Mie theory of light scattering. The particle size is reported as a volume equivalent sphere diameter. The instrument has an accuracy of 0.6%, operation temperatures of 5degC to 40degC (non-condensing), size of 10 nm - 3.5 mm (3000) or 0.1 - 1000 um (3000E).
