A particle size analyzer is an analytical instrument that measures, visualizes, and reports a particle size distribution for a given particle or droplet population. Particle size analyzers play an important role during process development and quality control of particle systems in order to develop efficient processes and achieve high final product quality.
Traditionally, sampling and offline particle size analyzers (laser diffraction, dynamic light scattering, sedimentation, or sieve rest analysis) were used for product quality control. However, common sampling challenges, increasing pressure to expedite process development, and a higher demand for "right first time" processes required the development of in situ particle size analyzer. The ability to measure particles as they naturally exist in a process has dramatically improved the ability to understand, optimize and control particle and droplet systems.
METTLER TOLEDO offers two different types of particles size analyzers. EasyViewer is an in situ video microscope that uses advanced image analysis to determine particles size. ParticleTrack is an in situ particle size analyzer that uses Focus Beam Reflectance Measurement (FBRM) to determine particle size.
