NIR Spectroscopy, or Near-Infrared Spectroscopy, is a technique that uses near-infrared light to analyze materials. It measures how light interacts with molecules, providing information about their chemical composition and structure. This method is widely used in various fields, including agriculture, pharmaceuticals, and food quality control, due to its speed and non-destructive nature. The process involves shining near-infrared light onto a sample and detecting the light that is reflected or transmitted. The resulting spectrum reveals specific absorption patterns, which can be correlated to the presence of different compounds. This makes NIR Spectroscopy a valuable tool for rapid analysis and quality assessment.
