Description:
The Mastersizer 2000 uses the laser diffraction technique to measure the size and particle size distribution of materials. This is carried out by measuring the intensity of light scattered when a laser beam passes through a sample of dispersed particles. The detectors measure light intensity for red and blue light. The data is analyzed to calculate the size of the particles that created the scattering pattern.
The equipment contains two sample dispersion units:
– Wet: for samples in solution, which can be applicable to different solvents.
– Dry: for solid samples in powder form, which are dispersed by a current of air.
Technical specifications:
• Particle size: 10 nm – 3.5 mm
• Measurement principle: Mie and Fraunhofer dispersion
