What is FT-NIR?

FT-NIR (Fourier Transform Near-Infrared) spectroscopy is an analytical technique that uses the near-infrared region of the electromagnetic spectrum (typically 780 nm to 2500 nm) to obtain information about the physical and chemical properties of a sample. FT-NIR spectrometers use an interferometer to generate an interferogram, which is then Fourier transformed to produce the NIR spectrum. It's commonly used for non-destructive analysis of materials in various industries, including pharmaceuticals, food, polymers, and chemicals, for quality control, process monitoring, and identification purposes.
