Fourier-Transform Infrared (FTIR) Spectroscopy Analysis
Envista’s Material Labs have invested in Fourier-transform infrared (FTIR) spectroscopy equipment to continue the growth of our materials analysis capability. Using specialized software, our FTIR analysis can help identify organic and inorganic compounds including those that may have been involved in a failure potentially leading to property damage, business interruption, personal injury, or fatalities. This analysis is most often used to ensure materials are performing as expected and are aptly suited for their intended application.
FTIR analysis can be used on various materials such as:
- Organic acids and salts
- Petroleum products, like greases and oils
- Fibers and textiles
The FTIR can help to determine causes of material failure such as:
- Product defects
- Manufacturing defects
- Installation issues
- Causes of stress cracking
- Special additives or missing additives
FTIR can be used to compare a subject item to a known sample, identifying what type of material it is, and possibly who manufactured it. We can determine if the subject item was manufactured incorrectly, has any defects, has or is missing any additives, and if there is any contamination, all of which can contribute to a failure of the material.
During this examination, our experts can compare samples to a database containing thousands of spectra from known materials, generating more finite answers for you and/or your clients. In addition to identifying the exact material, FTIR can also be used to determine if oxidation or decomposition has occurred.
How Does it Work?
FTIR is a chemically non-destructive analytical technique that can identify organic materials, including polymers and plastics. The instrument uses infrared light to scan a small sample of the material in question and produce a spectrum, a graph that shows which frequencies of IR light are absorbed. This information can be used to determine the chemical properties and structure of a material. The spectrum is unique to every substance, like a molecular fingerprint.
