FTIR Analysis
What is FTIR?

Fourier Transform Infrared Spectroscopy, also known as FTIR Analysis or FTIR Spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some cases, inorganic materials.

How does FTIR work?

The FTIR instrument sends infrared radiation of about 10,000 to 100 cm-1 through a sample, with some radiation absorbed and some passed through. The absorbed radiation is converted into rotational and/or vibrational energy by the sample molecules. The resulting signal at the detector presents as a spectrum, typically from 4000 cm-1 to 400cm-1, representing a molecular fingerprint of the sample. Each molecule or chemical structure will produce a unique spectral fingerprint, making FTIR analysis a great tool for chemical identification.

What is FTIR used for?

FTIR spectroscopy is an established technique for quality control when evaluating industrially manufactured material, and can often serve as the first step in the material analysis process.
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 additives after extraction from a polymer matrix
Identify oxidation, decomposition, or uncured monomers in failure analysis investigations
