The skilled labor shortage forces companies to simplify inspection processes. Fast and reliable cleanliness inspection is crucial to avoid production downtime and high costs. Modern grazing-light measurement systems combined with tape-lift sampling enable in-process, statistically validated monitoring of particulate contamination. The method delivers results in seconds, is mobile, and reduces training requirements. Thanks to its simple handling and automated evaluation, less qualified personnel can perform the inspections, reducing dependence on specialists while increasing process stability.
