Particle Measurement

We help you to answer the following questions:

  • Are the materials/assemblies cleanroom compatible?
  • Can the materials/assemblies be cleaned with low particle emission?
  • Is the achieved cleanliness reversible or non-reversible?

We apply the folllowing methods for the measurement of residual particles:

  • Surface measurement at  plane or slightly curved surfaces
  • Throughflow measurement of tubular components
  • Blowdown measurement at  complex structures
  • Measurement with ionized nitrogen as medium to achieve an additional cleaning effect

Ultrapure air and nitrogen are available as media for particle measurement. The counting and classification into 6 size classes from 0.3 µm to 10 µm by the particle measuring device is based on stray light originating from the particles. The measurements on the basis of  ISO 14644 and the VDI instruction 2083 are executed in clean room environment (ISO class 7 to ISO class 5) or under a clean room flow box (ISO class 1). The results are recorded in a standardized log.

We provide the following measurements as service for you:

  • Which cleaning process  generates a minimum particle load?
  • The mechanical application (bending, screwing, rubbing) generates particles. Which particle load is to be expected after usage?
  • Particle determination on a defined surface (considering particle class)
  • Particle load of clean room  cleaned components
