As for the analytical products ABB provide, the FT-IR technology is also used for the space missions. A Fourier Transform spectrometer is an optical instrument used to measure properties of light over a specific portion of the electromagnetic spectrum. This technology is a powerful tool for identifying types of chemical bonds in a molecule by producing an infrared absorption spectrum that is like a molecular "fingerprint". Molecular bonds vibrate at various frequencies depending on the elements and the type of bonds. For any given bond, there are several specific frequencies at which it can vibrate. This is the molecule “fingerprint” that our technology detects and can provide a qualitative or quantitative measurement.
