FT-IR Material Analysis

Chemist identifying white powder raw material by FTIR method
Introduction to FT-IR

Fourier-Transform Infrared Spectroscopy (FT-IR) material analysis is used to identify polymeric and organic materials. FT-IR analysis utilizes infrared radiation (IR) to scan and observe unknown materials. Our chemists use this technology to determine the identities of unknown sample materials by cross-referencing a spectral database containing thousands of different organic compounds and polymers.

How does FT-IR work?

FT-IR passes IR radiation through a thin sample.  Polymeric and organic materials are composed of functional groups that absorb IR radiation at specific wavelengths of energy. This absorption (and transmission) of energy produces a spectral molecular fingerprint. Each organic material has a unique spectral fingerprint which makes FT-IR useful for determining various unknown materials and confirming known materials in consumer products, foods, polymers, paints, and pharmaceuticals, to name a few. Given the unknown sample’s IR spectrum, we can then compare it to thousands of existing spectra in infrared radiation (IR) libraries and easily determine the sample’s identity. ATS chemists utilize FT-IR for a variety of other applications such as:

  • Purity Assessment
  • Material Analysis and Identification
  • Material Testing
Why use ATS’ FT-IR analytical services?

The ATS chemical analysis lab is equipped with a Nicolet 380 FT-IR which houses a low-pressure diamond anvil cell that can handle liquid and solid samples as small as half a millimeter in their natural state. At ATS, FT-IR analysis is virtually non-destructive in most cases.

ATS boasts a team of capable scientists working on various FT-IR analysis projects regularly. At ATS, we strive to provide unparalleled customer service by providing FT-IR analysis at a competitive price. We are dedicated to quality assurance by maintaining multiple accreditations and certifications including ISO 17025, 10CFR50 App. B, and ISO 9001. If you or your company require expeditious FT-IR testing and material analysis with reliable and accurate results, please contact Applied Technical Services for more information.
