Fourier Transform Infrared Spectroscopy

KSC's Analytical Laboratories branch provides Center-wide chemical analysis support for the identification of contaminants found in payloads, flight hardware, clean rooms, and processing facilities for programs such as Orion, and almost every payload launched from KSC including commercial operations. This is a common but very serious issue and there are stringent health and safety restrictions pertaining to foreign object debris and contamination in aerospace systems due to their extremely sensitive nature and potential to interface with the astronauts aboard the ISS. When contamination is discovered, such as fibers, particles, residues, etc., it is sampled and then analyzed to determine its identity. Fourier Transform Infrared spectroscopy (FTIR) is a critical component of this analysis.
