Aerolized adhesive coating has previously been shown to be as effective as conventional methods and may offer advantages
It is now widely recognized that coating of particle collection surfaces prior to impactor measurements is often necessary to avoid bias caused by particle re-entrainment of solid particles. The amount of re-entrainment is dependent on the particle and collection surface characteristics, but in most cases can be reduced or eliminated by applying a sticky material to the collection substrate.
