Near-Infrared Spectroscopy (NIR)

Near-Infrared Spectroscopy (NIR) is a technique that uses light in the near-infrared range to analyze the composition of substances. When NIR light shines on a material, some wavelengths are absorbed based on the chemical bonds present, while others are reflected. By measuring these changes, scientists can quickly determine the makeup of the sample, such as the moisture, fat, or protein content in foods, without destroying it. NIR is efficient, non-invasive, and widely used in industries like agriculture, pharmaceuticals, and food processing for rapid quality assessment.
