Fourier Transform Infrared

Fourier Transform Infrared Spectroscopy (FTIR) is an analytical technique used to identify organic (and in some cases inorganic) materials. This technique measures the absorption of various infrared light wavelengths by a particular material. The spectra are used to identify the material.

Absorption bands in the range of 4000 – 1500 wavenumbers are typically due to functional groups (e.g. -OH, C=O, N-H, CH3, etc.). The region between 1500 – 400 wavenumbers is referred to as the fingerprint region. Absorption bands in this region are generally due to intra-molecular phenomena, and are highly specific for each material. The specificity of these bands allow computerized data searches to be performed against reference libraries to identify a material.

At Peak Analytical, Inc., we utilize this advanced technique in the analysis of contamination and failures in plastics, rubbers, and others. Furthermore, our facilities also include various sampling accessories such as a gas cell, ATR, liquid cell, and a microscope to ensure that regardless of the sample type, we can obtain the best IR spectrum to perform a thorough analysis.

  1. We are a Michigan based supplier of water based heat exchangers and chillers. Looking at your product line-up you probably use water based cooling on some of your instruments? Is there any opportunity to supply chillers to Peak as an OEM supplier? We would be interested in talking if there is interest. Please let me know if there is an opportunity or not. 70% of our business are special designs for end customers and OEM’s.

    Hi Greg,
    I would like a budgetary quote for performing specular and diffuse reflection measurements at a wavelength of 10.6 microns (wavenumber 943 cm-1). We would want about 10-20 samples measured, sample size is about 15mm round.

    Work would occur in the May-June time frame, would like 2-3 week turnaround.
