Once again, the specter of contaminated eye drops reaching patients has made headlines, according to the FDA, federal investigators found harmful bacteria and “insanitary conditions” at a factory where several eye drop products are made. The agency said it advised the manufacturer to recall the products.
The newly published ISO/TR 14644 part 21 provides clarification on the application of sound airborne particle sampling techniques in support of ISO 14644-1:2015 for classification of cleanrooms and clean zones, and ISO 14644-2:2015 for airborne particle monitoring, to provide evidence of cleanroom performance related to air cleanliness by particle concentration.
This paper discusses the goal to minimize microplastics in aquatic systems and validating the results. The authors of this paper propose a new approach of measurement and filtration that has the opportunity to reduce the microplastics that end up in our water. This alternative method would allow manufacturers to measure particles in treated textile water continuously for particles that are as small as 2.0 microns.
Pinpointing a particle source can be a challenge in cleanrooms and laboratory flow equipment where the movement
