Research Abstract

Removal efficiency of air filters for nanoparticles is of great concern in relation to risk management of functional nanomaterials in various manufacturing process. The present work investgated the application of monodispersed macromolecular ions as a substitute of nanoparticles for testing the performacne of air filters. As a result we found out that poly-ethylene-glycol (PEG) ions can be used to test air filters for nanoparticles larger than 2.6 nm when they are sprayed by electrospray following by the neutrization and classification with a differential mobility analyzer.
