Steel canisters (grab samples) for VOC measurements. Up to 8 samples can be taken automatically during the flight.
The samples were analyzed at IFU (Fraunhofer Institut für Atmosphärische Umweltforschung in Garmisch-Partenkirchen).
The samples are a supplement to the in-situ gaschromatography, extending the C-range down to C2, and allowing
comparisons in the range C4-C6.
