Near-Infrared Spectroscopy

Near-Infrared Spectroscopy (NIRS) is a technique that uses specific types of light—near-infrared light—to analyze the composition of materials. When this light is directed at a sample, some wavelengths are absorbed, while others pass through or are reflected back. By measuring these absorbance patterns, scientists can determine the presence and concentration of compounds like water, fats, or proteins without damaging the sample. NIRS is useful in various fields such as medicine, agriculture, and food quality control, offering a fast, non-invasive way to gather detailed chemical information.
