Particle Sizing

Particle Sizing

Particle Technology has a range of analytical equipment for particle sizing of metallic particles or powders, this range of methods enables us to analyse particle sizes from nanometres to millimetres.

Horiba Partica LA-950

The LA-950 can measure particles in the range of 10nm to 3000um and is used for both dry powders and suspensions.

Beckman Coulter MultiSizer 3

The Multisizer 3 has an overall sizing range of 0.4um to 1200um and will provide number, volume, mass and surface area size distributions and its response is unaffected by particle colour, shape, composition or refractive index

Hiac Royco 8000A

The 8000A is used primarily for testing Hydraulic fluid to ISO Standard 4406 and has an overall size range from 1.2um to 100um

Image Analysis Microscopy

Image analysis allows us to identify a particles shape in addition to size and number, it also allows us to characterise material that was previously very difficult such as fibres and needles.


Sieve analysis is one of the oldest techniques for measuring particle size distributions, it is also one of the methods that can be used for fractionation. We have a range of sieves from 20um to 3000um which can be stacked on a sieve shaker and used either wet or dry.

Bulk Powder Properties

In addition to the range of particle sizing equipment we also have the facilities for manipulation of powder properties by measuring, adjusting and controlling the particle size distribution. Using our labs and pilot plant facilities we can produce small scale batches for R&D trials and ongoing small scale production.

Analytical tools and methods are available for the measurement of the following bulk powder properties;

  • Bulk Density
  • Compacted or Tap Density by Auto-Tap
  • True Density using Pycnometer
  • Density of Liquid Slurry by Hydrometer
  • Effects of Temperature up to 400Âșc
  • Effects of Humidity/Water
  • Chemical Analysis, presence of water, hydrocarbons, volatiles
  • Angle of repose (powder flow properties)
  • pH
  • Total Suspended Solids
  • Total Dissolved Solids
  • Volatiles (organic or water)
