Particle Sizing Systems

AccuSizer Micron Counting and Sizing



The success of the AccuSizer range of sensors in the laboratory has been extended to On-Line operations to detect particle outliers in processes such as homogenization, grinding and filtration.

A typical application for these systems is the monitoring of a critical In-line filter such as CMP (chemical mechanical polishing) slurry production.

The multiplex sampling hydraulics allow:

  • Sampling from an unfiltered, upstream line with suitable autodilution.
  • Sampling from the filtered product stream with the appropriate autodilution to achieve optimum counts through the detection system.


  • The LE400 sensor; collimated beam, scatter + extinction, 0.5-400µm
  • The LE1000 sensor; extinction only, 2-1000µm
  • The LE2500 sensor; extinction only, 25-2500µm
  • The FX; focused beam, extinction 0.7-20µm at high concentration
  • The FX Nano; focused beam, scattering 0.15-10+ µm at high concentration


  • The counter provides high resolution results in up to 512 size channels.


  • The sample can be transported through the sensor either without dilution or with single and two stage auto-dilution samplers.
