Cassini Ion Neutral Mass Spectrometer
The INMS is capable of determining the chemical, elemental and isotopic composition of the gaseous and volatile components of the neutral particles and the low energy ions in Titan's atmosphere and ionosphere, Saturn's magnetosphere, and the ring environment.
The INMS measures neutral gas and low energy ions using two gas inlets. The mass-to-charge analyzer is a quadrupole radio frequency spectrometer and there are two secondary electron multiplier detectors. The INMS is mounted on the Fields and Particles Platform of the Cassini spacecraft.
