Cleanrooms couldn’t function without accurate air particle measurement. Consistent monitoring, whether done by in-house staff or a third party vendor, is critical to maintaining a necessary level of cleanliness for specific controlled environments.
The frequency of air particle measurement will differ, depending on the needs of the product or the requirements of the company. However, in a controlled environment, there is always some kind of monitoring going on.
“If you’re processing in an aseptic environment, the general rule is to be doing some type of monitoring every shift,” says Anne Connors, regional marketing manager, North America, Environmental Monitoring, EMD Millipore, Billerica, Mass.
This cleanroom tip was taken from “Measuring Air Particles,” which appeared in the January 2013 issue of Controlled Environments.
