Aerosol mass spectrometry is the application of mass spectrometry to the analysis of the composition of aerosol particles.[1] 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[2] and are produced from natural and anthropogenic sources, through a variety of different processes that include wind-blown suspension and combustion of fossil fuels and biomass. Analysis of these particles is important owing to their major impacts on global climate change, visibility, regional air pollution and human health.[2][3] Aerosols are very complex in structure, can contain thousands of different chemical compounds within a single particle, and need to be analysed for both size and chemical composition, in real-time or off-line applications.
Off-line mass spectrometry is performed on collected particles,[2] while on-line mass spectrometry is performed on particles introduced in real time.[4]
