ACP's main objective is the chemical analysis of the aerosols in Titan's atmosphere. For this purpose, it will sample the aerosols during descent and prepare the collected matter (by evaporation, pyrolysis and gas products transfer) for analysis by the Huygens Gas Chromatograph Mass Spectrometer (GCMS). A sampling system is required for sampling the aerosols in the 135'32 km and 22'17 km altitude regions of Titan's atmosphere. A pump unit is used to force the gas flow through a filter. In its… 
The Gas Chromatograph Mass Spectrometer for the Huygens Probe
The Gas Chromatograph Mass Spectrometer (GCMS) on the Huygens Probe will measure the chemical composition of Titan's atmosphere from 170 km altitude (∼1 hPa) to the surface (∼1500 hPa) and determine
Composition of Titan's Surface
The Huygens Probe returned the first in situ data on Titan's surface composition in January 2005. Although Huygens landed on a dry plain, the Gas Chromatograph Mass Spectrometer (GCMS) showed
Can laboratory tholins mimic the chemistry producing Titan's aerosols? A review in light of ACP experimental results
The first results obtained by the ACP experiment onboard Huygens probe revealed that the main products obtained after thermolysis of Titan's collected aerosols, were ammonia (NH3) and hydrogen
Chapter 6 Composition of Titan ’ s Surface
Abstract The Huygens Probe returned the first in situ data on Titan’s surface composition in January 2005. Although Huygens landed on a dry plain, the Gas Chromatograph Mass Spectrometer (GCMS)
PAMPRE: A dusty plasma experiment for Titan's tholins production and study
Organic aerosols play a significant role in the properties and evolution of Titan's atmosphere. But our knowledge of them and their physico-chemical mechanisms of formation and evolution are
Performances under representative pressure and temperature conditions of the gas chromatography-mass spectrometry space experiment to investigate Titan's atmospheric composition.
An analytical database is created that can be used as a reference to treat the chromatograms obtained in situ, and help to identify chromatographically the analyzed species, complementary to mass spectrometry.
The abundances of constituents of Titan's atmosphere from the GCMS instrument on the Huygens probe
Direct atmospheric measurements from the Gas Chromatograph Mass Spectrometer (GCMS), including altitude profiles of the constituents, isotopic ratios and trace species (including organic compounds), were reported, confirming the primary constituents were confirmed to be nitrogen and methane.
Optical spectroscopy investigation of N2–CH4 plasma jets simulating Titan atmospheric entry conditions
Planetary probes penetrating at supersonic speed into high atmosphere require the development of composite materials for thermal protection of the surface exposed to a high enthalpy flux. Rarefied
The composition of Titan’s lower atmosphere and simple surface volatiles as measured by the Cassini-Huygens probe
The Cassini-Huygens Probe Gas Chromatograph Mass Spectrometer (GCMS) determined the composition of the Titan atmosphere from ~140km altitude to the surface. After landing, it returned composition

The designers of the Huygens probe claim to have detected complex organic matter in two aerosol samples collected at different altitudes, on the basis of their detection of ammonia (NH3) and hydrogen cyanide (HCN) when the sample oven was heated to 600 °C.


New planetary atmosphere simulations: application to the organic aerosols of Titan.
A "Titan aerosol generator" was developed in the frame of the Cassini-Huygens mission, in order to produce Titan's aerosol analogues within conditions closer to those of the titanian atmosphere: cold plasma simulation system, low pressure and low temperature.
Analytical pyrolysis experiments of Titan aerosol analogues in preparation for the Cassini Huygens mission.
Comparative pyrolysis mass spectrometric data of Titan aerosol analogues, called "tholins", are presented to provide a basis for modelling of aerosol composition on Titan and for the interpretation of Titan atmosphere data from the Huygens probe in the future.
