FTIR Analysis (Fourier Transform Infrared Spectroscopy)

FTIR Analysis & Testing –Innovatech LabsAre you seeking ways to determine precise material composition, identify contaminants and provide better quality control when it comes to your products? FTIR analysis can make that possible.

Innovatech Labs uses FTIR Analysis (Fourier Transform Infrared Spectroscopy) as a technique to identify organic (and in some cases inorganic) materials. FTIR Analysis is used to:

  • Identify unknown materials

  • Identify and/or quantify surface contamination on a material

  • Identify additives in a polymer, when they can be chemically removed, e.g. solvent extraction.

FTIR Analysis is often the first step in the materials analysis process because of its speed and simplicity. It can also be a particularly precise tool for identifying unknown material and enhancing quality control.

FTIR analysis measures the range of wavelengths in the infrared region that are absorbed by a material. This is accomplished through the application of infrared radiation (IR) to samples of a material. The sample's absorbance of the infrared light's energy at various wavelengths is measured to determine the material's molecular composition and structure.

FTIR analysis testing can also provide:

  • Precise measurements

  • Analysis with little or no harm to the sample

  • Sample information collection at high speed

Samples as small as 10 microns can be evaluated using FTIR analysis. The tiny sample size allows for cost effective identification of particles, residues, films or fibers. FTIR analysis can also measure levels of oxidation or degrees of cure in some polymers as well as measuring the level of contaminants or additives.

Unknown materials are identified by searching the spectrum against a database of reference spectra. Materials can be quantified using the FTIR materials characterization technique as long as a standard curve of known concentrations of the component of interest can be created.
