Fourier Transform Infra-Red Spectroscopy (FTIR)
What is Fourier Transform Infra-Red Spectroscopy (FTIR)?
Named for the use of the Fourier transform mathematical process, Fourier transform infra-red spectroscopy converts raw data into an infrared spectrum of absorption or emission of a solid, liquid or gas.
FTIR spectroscopy is a vital analytical technique used in laboratories around the world due to its versatility and simplicity. It is non-destructive and delivers fast, on-site results thanks to advanced handheld technology.
FTIR spectrometers simultaneously collect high spectral resolution data over a wide spectral range. Compared to a dispersive infra-red spectrometer, which measures intensity over a narrow range of wavelengths at a time, FTIR analysis is performed at a much faster rate.
How Does FTIR Work?
As mentioned, Fourier transforms infrared spectroscopy uses the mathematical transform called the Fourier Transform, which decomposes functions depending on space or time into functions depending on spatial or temporal frequency.
The use of this transform in FTIR allows us to convert the detector signal from a time domain into the frequency domain, resulting in the FTIR spectrum.
Common Applications For FTIR
Polymers and Surface Coatings
When polymers and plastics absorb infrared light, typically in the mid-infrared region, the resulting spectrum reveals a distinctive quality that can be used to quickly screen and test samples.
Our range of Fourier Transform-Infrared Spectrometers are reliable and cost-effective analytical instruments for the detection of polymers and the analysis of plastic materials.
Mineral Identification
FTIR spectroscopy is an established technique for determining qualitative mineral identification. This is possible because minerals have characteristic absorption bands in the mid-range of the infrared.
Our FTIR devices make this mineral identification technique fast and non-destructive.
Safety Detection of Degradation
FTIR spectroscopy is a powerful and accurate device in the studies on degradation products that are formed due to aging or deterioration.
Soil Science
Since FTIR spectroscopy is a fast, low-cost, and insightful measurement, it is commonly used as a complement or replacement for more expensive and less practical soil analysis tools.
Historical Artefacts
FTIR spectroscopy can be used for the dating of a wide range of historical and artistic artefacts. The technique is popular because its small samples can be directly analysed quickly and effectively.
Quality Control
FTIR spectroscopy provides powerful analytical opportunities in many areas of production and quality control. It covers a variety of chemical applications, especially in the analysis of
organic compounds.
At Portable Analytical Solutions, we have a wide range of FTIR spectrometers that address the quality control and quality assurance needs in laboratories.
