Email About Fourier Transform Infrared Spectroscopy Infrared spectroscopy IR spectroscopy is the subset of spectroscopy that deals with the infrared region of the electromagnetic spectrum. It can be used to identify compounds or investigate sample composition.

Important Regions of the IR Spectrum

The infrared spectrum of a sample is collected by passing a beam of infrared light through the sample. Examination of the transmitted light reveals how much energy was absorbed at each wavelength. This can be done by using a Fourier transform instrument to measure all wavelengths at once.

From this, a transmittance or absorbance spectrum can be produced, showing at which IR wavelengths the sample Ftir interpretation. Analysis of these absorption characteristics reveals details about the molecular structure of the sample.

Approaches The Infrared Spectrometer provides data over the range from to cm-1 with the main instrument bench and a somewhat narrower range of analysis to approximately cm-1 when an attenuated total reflectance accessory is used. Thin coatings can be evaluated directly on a reflective substrate reflection-absorbance mode and powder materials can be evaluated using the diffuse reflectance mode.

Samples can be solids, liquids, or gases. Small samples can be analyzed within the instrument; larger samples can be analyzed using an external microscope accessory.


The microscope can also be used to target a specific portion of a sample. Solids and liquids are most commonly evaluated using FTIR spectroscopy. The solid materials can be thermoset or thermoplastic materials, rubber materials, coating, fibers, and virtually any manufactured product.

Liquid samples include lubricants, solvents, contamination that has been swabbed away from a surface, and any other liquid whose identity must be determined. Contact us to talk through your specific sample considerations.

 Interpretation, most often misunderstood by the public as alternative or auxiliary to translation, instead is a rendition process of a message verbally presented in one language being reproduced into the other language extempore. FTIR spectroscopy is an analytical measurement method to characterize and identify the structure of organic molecules.

In oil analysis, we are analyzing in-service lubricants to detect. Smith has written three books on infrared spectroscopy: Fundamentals of FTIR and Infrared Spectral Interpretation, both published by CRC Press, and Quantitative Spectroscopy: Theory and Practice published by Academic Press.


He has published a number of papers in peer-reviewed journals and is a co-inventor on a patent for an FT .
