![]() FTIR also has a higher signal-to-noise ratio and high wavelength preciseness, making it more accurate than traditional IR spectroscopy. This makes FTIR more effective time-wise when compared to a traditional dispersive IR spectroscopy technique. The wide spectral range allows multiple frequencies of light to be directed at the sample at the same time. This is made possible by a special arrangement of fixed and movable mirrors in the interferometer. Advantages of FTIR compared to traditional IR spectroscopyįTIR allows precise and simultaneous spectral data collection with a wide spectral range. The final form represents light intensity as a function of wavenumber. The raw data is converted to a spectrum-friendly form via a mathematical process called Fourier transform. Collected data represents the intensity of light as a function of the position of a movable mirror inside the interferometer. The amount of absorption and emission of IR light in the sample is measured with a detector. Different molecules and bonds vibrate in their own specific way. When different molecules absorb IR light, molecular vibration occurs. The measured material (solid, liquid, or gas) is subjected to an infrared light spectrum. The operating principle of FTIR spectroscopy The technique is capable of quantifying different types of microplastic particles in several size ranges. FTIR spectroscopy can also be used to identify microplastics in water samples. Some of the most common applications include identifying chemical components in solid and aqueous samples. FTIR is an effective analytical tool for material identification. ![]()
