Fast Analysis of Volatile ORganics with gas chromatography/mass spectrometry on HALO

Volatile organic compounds have great influence on the radical chemistry.

General Information on organic trace gases

Despite their importance, there are only few data on the concentration and distribution of these compounds in the upper troposphere. Aim of the project is the construction and the use of a fast gas chromatograph/mass spectrometer on the research aircraft (HALO).

The GC/MS is to collect data on nonoxygenated and oxygenated organic trace gases in the HALO mission OMO. A particular challenge is the development of a fast system to obtain data with a high time resolution. The project is promoted by the DFG within the priority program ' high altitude and long range research aircraft’ (HALO).
