Analysis of the particulate & filmic cleanliness

In the field of analytics, we evaluate the particulate and chemical-filmic component cleanliness of your products and assist you in detection the particle source by determining the material of the particles.

Particulate Contamination

Cleanliness inspections acc. VDA 19.1 / ISO 16232:2018 as well as over 1,000 specific customer standards

  • Standard cleanliness inspections
  • CCPlus cleanliness inspections with increased blank value requirements and fibers under laminar flow conditions
  • Cleanliness inspections of large components up to approx. 1.500 mm edge length with special extraction equipment for large components (large component extraction cabinet, large component manipulator)
  • Cleanliness inspection by means of fair jet extraction acc. VDA 19.1, chapter 6.5.1 of non-wet extractable components
  • Cleanliness inspections with air throughflow extraction acc. VDA 19.1, chapter 6.5.2 of air-conducting components
  • Cleanliness inspections with suction extraction (with air with particle suction extraction system C|PS²) of oversized components or directly in the process environment as well as the evaluation of the extracted particles
  • Cleanliness quick test using particle stamps (e.g. on component packaging)
  • Microscopic evaluation of particle traps/stamps
  • Construction and production of test equipment and adapters
