FTIRlaineanalüüs

FTIRlaineanalüüs, also known as Fourier Transform Infrared Spectroscopy analysis, is a widely used analytical technique in chemistry and material science. It relies on the principle that molecules absorb specific frequencies of infrared light, which causes their bonds to vibrate. By analyzing the pattern of absorbed infrared light, a unique spectral fingerprint for each substance can be generated. This fingerprint allows for the identification and quantification of unknown compounds, as well as the characterization of materials.

The process involves passing an infrared beam through a sample. A detector measures the amount of light that is transmitted or reflected. This raw data, known as an interferogram, is then processed using a mathematical algorithm called the Fourier Transform. The Fourier Transform converts the interferogram into a spectrum, which plots the absorbance or transmittance of infrared radiation against wavenumber (a unit related to frequency). Different functional groups within a molecule absorb infrared radiation at characteristic wavenumbers, providing valuable information about the chemical structure. FTIRlaineanalüüs is non-destructive, meaning the sample is typically not altered during the analysis, allowing for further testing if needed. It is applied in diverse fields including pharmaceuticals, environmental monitoring, food analysis, and polymer science for quality control, research, and problem-solving.
