Analyzing Air Nanoparticulates

Abstract:
The chemical composition of airborne nanoparticles is largely unknown because of measurement difficulties. Chemists at the University of Delaware, Newark, have now developed a nanoaerosol mass spectrometer that combines an aerodynamic inlet, an ion trap, and a time-of-flight mass analyzer to characterize individual particles smaller than 10 nm.
