Fourier transform infrared spectroscopy

The specimen is illuminated with infrared light to measure the transmitted or reflected light.
Due to differences in the molecular structure of the substances that make up the sample, it has been found that some of the irradiated infrared light is used as energy for the molecules to oscillate or rotate at a specific wavelength. By analyzing the spectral pattern obtained from measurement, information on the molecular structure and sensual groups of substances can be obtained.

It enables structural analysis of organic compounds and plastics.
It is also possible to compare the measured spectrums side by side, or compare it with the database to compare it with typical sample data.

Since the transmission and reflected light irradiated on the sample, it is not good at measuring black substances (rubber, etc.) that absorb light is not good. In addition, while the structure of organic matter can be analyzed, accurate information on the types of inorganic elements cannot be obtained. Foreign substances that adhere to very thinly and seeps into the substrate, or substances that have deteriorated due to heat or light, may differ from the structure before degradation.
