operational principle

The Mastersizer 3000 laser particle size analyzer uses laser diffraction technology to measure particle size. When the laser beam passes through dispersed particle samples, particle size measurement is completed by measuring the intensity of scattered light. Then the data is used to analyze and calculate the particle size distribution that forms the scattering spectrum.

A typical system consists of three main components:

Optical platform-The dispersed samples pass through the measurement area of the optical platform, where the laser beam is irradiated onto the particles. When red and blue light illuminate sample particles, scattering occurs over a wide angle, and a series of detectors can accurately measure the scattered light intensity of particles.
Sample dispersion device (attachment).The sample dispersion is controlled by a series of wet and dry dispersion devices. Ensure that particles are transported to the measurement area of the optical platform at the correct concentration and in a suitable and stable dispersion state.
Instrument software:Mastersizer 3000 software controls the system during the measurement process, analyzes scattering data, and calculates particle size distribution. The software can also provide immediate feedback during the method development process and provide professional advice on the quality of results.
