Count Control Particles

Calibrate and check laser particle counters

Validate the results of particle counters with Thermo Scientific™ Count Controls to make sure they are measuring particulate matter with utmost accuracy. This is critical wherever air, surface or liquid contamination is a concern and requires diligent monitoring. Otherwise, users risk working with potentially misleading and inconsistent data that could lead to costly, time-consuming errors. With a diameter traceable to the National Institute of Standards and Technology (NIST), our Count Controls provide the confidence and paperwork required by QC that the particle counter is doing precisely what it is intended to do.

Key Applications

  • Instrument calibration and validation of particle counters using laser scatter, light scatter, light blockage, imaging, microscopy, and electrical resistance
  • QC checks for instrument problems and shifts in laser function, check the calibration curve shape, etc.
  • Monitor for particulate matter in the manufacture of parenteral drugs and ophthalmic solutions
