What does a particle size analyzer do?

The size and distribution of the particles that make up a substance are identified using particle analyzers. Particle size analyzers are employed in a variety of industries for product testing, production, quality control, and research and development.

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.

  • Catalyst – maximum surface area
  • Medicines – highest bio-availability
  • Industrial processing – good flowability

Particle size analysis is important for process optimization and quality control to ensure and document optimal particle properties. 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.

What is particle size measured in?

Particle size analyzers measure particles in a length dimension like nm, µm, or mm. Depending on the industry and particles, a different size range can be applied.

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. The average particle size provides one averaged number that characterizes a larger particle population.

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. There are a variety of particle size analyzers available. All particle size analyzers provide different values for the same particle, depending on their specific method of measurement.

How do you measure the size of a particle?

Macroscopic particles can, for example, be measured with a ruler or caliper. Microscopic crystals usually need more sophisticated analytical devices due to the reduced particle size. Typical particle size measurement techniques are image analysis, laser back-scattering, laser diffraction, or sieve fraction analysis.

What does particle size mean?

Every particle has a specific shape and different three-dimensional elongation. Particle size is an effective way to describe and characterize the dimensional properties (length, width, and height) of a particle. 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.
