Abstract
A miniature mass spectrometer that may be coupled to an atmospheric pressure ionisation source is described. Ions pass through a small orifice from a region at atmospheric pressure or low vacuum, and undergo efficient collisional cooling as they transit a very short, differentially pumped ion guide. A narrow beam of low energy ions is passed through a small aperture and into a separate chamber containing the mass analyser.
