Particle Analysis & Particle Size Laboratories
Particle analysis characterises size distribution, shape, count and composition of particulate matter, whether in a bulk powder, a fluid or as contamination on a surface.
What does it measure?
- Particle size distribution
- Particle count by size band
- Shape and morphology
- Particle composition (with SEM/EDS or spectroscopy)
When is it used?
- Powder qualification for manufacturing
- Cleanliness verification of components and fluids
- Contamination investigations
- Filtration and process performance
Sample considerations
- Sampling method strongly affects results; representative sampling matters more than sample size.
- For cleanliness work, state the extraction method and acceptance limits.

Frequently asked questions
- Which technique gives particle size?
- Laser diffraction, dynamic image analysis, sieving and microscopy are all used. The right choice depends on the size range, material and the standard you must follow.
