GCMS - Gas Chromatograph Mass Spectrometer

Overview

The Huygens Gas Chromatograph Mass Spectrometer (GCMS) was designed to provide an accurate analysis of Titan's atmospheric composition along the descent trajectory of the Huygens Probe. It measured the altitude profiles of the atmospheric constituents, isotopic ratios, and trace species.

Data Example

Plot of methane mole fraction as a function of time (and therefore altitude) as measured by Huygens/GCMS.
