What is a FTIR spectrometer?

An FTIR spectrometer (Fourier Transform Infrared Spectrometer) is an instrument used to analyze the molecular structure and chemical composition of materials by measuring molecular vibrations and rotations using infrared light. When infrared light is directed at a sample, specific wavelengths are absorbed depending on the chemical bonds and molecular composition within the material. The resulting spectrum provides information on the types and quantities of chemical bonds, allowing identification of the material’s unique characteristics. FTIR spectrometers are widely used in fields such as chemistry, pharmaceuticals, food science, and environmental science for applications like component analysis, impurity detection, and tracking decomposition reactions. Because it enables rapid, non-destructive analysis, FTIR is valuable for quality control and research and development.

Application of FTIR spectrometer

１．Food Quality Control
In the food industry, FTIR spectrometers are used for component analysis and detecting contaminants. For instance, when analyzing the oxidation state of fats, FTIR can quickly detect changes in the chemical structure due to oxidation, aiding in effective quality control.
２．Detection of Environmental Pollutants
In environmental science, FTIR spectrometers are used to detect pollutants in soil and water. For example, FTIR can identify specific organic compounds in contaminated soil caused by petroleum or organic solvents, allowing for assessment of pollution levels.
３．Purity Check in Pharmaceuticals
In pharmaceutical manufacturing, FTIR spectrometers help verify the purity of drugs and detect impurities. During production, FTIR enables quick quality checks to ensure that drug components are correctly formulated and free from unwanted contaminants.
