NIRjärjestelmä

NIRjärjestelmä, which translates to NIR system, refers to a technology utilizing near-infrared (NIR) spectroscopy for analysis. NIR spectroscopy is a type of molecular spectroscopy that measures the absorption of light in the near-infrared region of the electromagnetic spectrum, typically between 780 and 2500 nanometers. This region is characterized by overtones and combination bands of molecular vibrations, making it sensitive to the presence of organic molecules.

The core principle of NIRjärjestelmä involves shining a beam of near-infrared light onto a sample. Different chemical bonds within the sample absorb specific wavelengths of this light. A detector measures the transmitted or reflected light, creating a spectrum that is unique to the sample's chemical composition. This spectrum can then be analyzed using chemometric methods, such as regression models, to quantify various components or identify the material.

NIRjärjestelmä finds widespread applications across diverse industries. In agriculture, it is used for determining the quality of grains, forages, and food products, measuring parameters like moisture content, protein, and fat. In the pharmaceutical industry, it aids in raw material identification, quality control of finished products, and process monitoring. The chemical industry employs it for identifying polymers, monitoring reactions, and analyzing various chemical compounds. Furthermore, NIRjärjestelmä is utilized in the plastics industry for material sorting and identification, and in the food and beverage sector for analyzing ingredients and ensuring product consistency. Its non-destructive nature, rapid analysis speed, and minimal sample preparation requirements make it a valuable analytical tool.
