Innovation application: Fourier Transform Infrared (FTIR) Measurements

Title Fourier Transform Infrared (FTIR) Measurements

The Infrared Fourier spectroscopy is based on the use of the Fourier transformation method. FTIR spectrum helps to identify specific chemical bounds in material, and, if the FTIR spectrum is known, this method can be used to identify specific materials/substances. This method is non-destructive. Solids, gases and solutions can be studied by this method.

Description of the technology

We propose the measurement of FTIR spectra in the range from 8000 to 550 cm-1. The FTIR spectrometry is a method, which is based on oscillations of bounds. It allows to obtain spectra of a higher quality as compared to those of the usual IR spectrometry, which is related to the Fourier treatment. As a result, the influence of noise on the spectrum is reduced. The FTIR equipment contains extra module, which is applicable for the analysis of solids, liquids, pastes, jellies and unknown materials.

Applications FTIR spectroscopy can be used to identify specific chemical bounds and even chemical composition of the substance.

This method is non-destructive and can be used to analyze chemical composition of the material.
