Quick Overview

Fourier-transform infrared spectroscopy (FTIR) is an analytical technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high-spectral-resolution data over a wide spectral range.

* Required Fields



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. A change in the characteristic pattern of absorption bands clearly indicates a change in the composition of the material or the presence of contamination. If problems with the product are identified by visual inspection, the origin is typically determined by FTIR microanalysis. This technique is useful for analyzing the chemical composition of smaller particles, typically 10 -50 microns, as well as larger areas on the surface.

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
