FTIR analysis is used to: Identify and characterize unknown materials (e.g., films, solids, powders, or liquids) Identify contamination on or in a material (e.g., particles, fibers, powders, or liquids) ... Identify oxidation, decomposition, or uncured monomers in failure analysis investigations.

What is FTIR used for?

FTIR spectra reveal the composition of solids, liquids, and gases. The most common use is in the identification of unknown materials and confirmation of production materials (incoming or outgoing). The information content is very specific in most cases, permitting fine discrimination between like materials.

What information can FTIR provide?

FTIR is a rapid, nondestructive, time saving method that can detect a range of functional groups and is sensitive to changes in molecular structure. FTIR provide information on the basis of chemical composition and physical state of the whole sample (Cocchi et al. 2004).
