Design of an aerosol mass spectral interface

摘要

Under a Cooperative Agreement sponsored by EPA's National Risk Management Research Laboratory, Aerosol Mass Spectral Interface (AMSI) has been designed, constructed, and evaluated. The AMSI is a portable inlet system for aerosol chemical analysis by mass spectrometry. The aerosol product is analyzed real-time, on-line using the mass spectrometer (MS) to perform separations. The AMSI can also be operated to introduce only specific sizes of aerosol particles into the MS allowing for chemical characterization based on particle size. The AMSI has been successfully coupled with a particle beam MS and an atmospheric MS.
