Scientific Results obtained with ACP experiment

The Aerosol Collector Pyrolyser (ACP) experiment is one of the six experiments by the Huygens Probe. Its scientific objective is to determine the chemical composition of the aerosols of Titan's atmosphere. The aerosols are collected via filtration during the descent, and are then analysed using the GCMS-Pyrolysis technique. For this technique, the instrument is in direct interface with another of the probe's instruments: the Gas Chromatograph Mass Spectrometer (GCMS), the main objective of which is to determine the chemical composition of the atmospheric gases. The identification of the gases coming from the ACP oven is carried out by this instrument which is used as a chemical analyser. All the data relating to transfers are sent to those running the ACP experiment, who proceed with the scientific analysis.
