Near Infrared SpectroscopyNear-infrared (NIR) spectroscopy measures the interaction of near-infrared light with a sample, including transmission, reflectance and absorbance, facilitating the identification of analytes. Measurements can be conducted using a Fourier-transform near infrared (FT-NIR) spectrometer, while there are also UV-Vis- NIR spectrophotometers that measure a broader spectrum of wavelengths.
