How Does a Particle Size Analyzer Work? A particle size analyzer operates according to a specific method of measurement (for example, image analysis, laser back-scattering, or laser diffraction) with individual and method specific boundary conditions. The average particle size provides one averaged number that characterizes a larger particle population. What is the Average Particle Size? For particle populations of many different particle sizes (small to large) it is possible to calculate the arithmetic mean, median or mode as an integral function over all particles. Typical particle size measurement techniques are image analysis, laser back-scattering, laser diffraction or sieve fraction analysis. Microscopic crystals usually need more sophisticated analytical devices due to the reduced particle size. How Do You Measure Particle Size? Macroscopic particles can, for example, be measured with a ruler or caliper.

Depending on the industry and particles, a different size range can be applicable. What is Particle Size Measured In? Particle size is measured in a length dimension like nm, µm, or mm. The wrong particle size, in the worst case, can mean that a particle product will not be fit-for-purpose and a downstream process might experience an unplanned shutdown. Particle size analysis is important for process optimization and quality control to ensure and document optimal particle properties.

Industrial Processing – Good Flowability.

Why is Particle Size Analysis Important? Different particles can have very different physical properties and a certain particle size and shape will be optimal for a specific purpose. Although particles are usually of three-dimensional nature, a one-dimensional size function (for example, chord length, particle length or spherical equivalent diameter) is frequently used in practice. Particle size is an effective way to describe and characterize the dimensional properties (length, width, and height) of a particle. What Does Particle Size Mean? Every particle has a specific shape and different three-dimensional elongation. ParticleTrack is an in-situ particle size analyzer that uses Focus Beam Reflectance Measurement (FBRM) to determine particle size. EasyViewer is an in-situ video microscope that uses advanced image analysis to determine particles size. METTLER TOLEDO offers two different types of particles size analyzers. 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. 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.

Traditionally, sampling and offline particle size analyzers (laser diffraction, dynamic light scattering, sedimentation or sieve rest analysis) were used for product quality control. 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. A particle size analyzer is an analytical instrument that measures, visualizes and reports a particle size distribution for a given particle or droplet population.
