Aerosol mass spectrometry - Wikipedia
Aerosol mass spectrometry is the application of mass spectrometry to aerosol particles. Aerosol particles are defined as solid and liquid particles suspended in a gas (air), with size range of 3 nm to 100 μm in diameter. Aerosol particles are produced from natural and anthropogenic sources, through a variety of different.
