We appreciate you letting us know that reducing variability in APSD measurement is a key area of interest.
APSD measurement can be affected by a range of factors, from device handling and flow control through to impactor set-up, sample recovery and environmental conditions. Understanding where variability enters the workflow is an important step towards improving repeatability and confidence in results.
Explore the resources below to learn more about common sources of APSD variability and practical approaches to reducing them.
