Short summary

The design of an ion trap aerosol mass spectrometer was improved, allowing for the instrument's first field deployment. Detection limits were found to be sufficiently low for ambient measurements. Via MS-MS measurements the instrument is capable of differentiating ion fragments of different elemental compositions, but also fragments which only differ in their molecular structures. This could allow for e.g. the differentiation between sugars and carboxylic acids by MS–MS studies on m/z 60 and 73.
