NIRanalyysillä

NIRanalyysillä refers to the analysis of samples using Near-Infrared (NIR) spectroscopy. This technique utilizes the absorption of near-infrared light by a sample to determine its chemical composition. NIR spectroscopy works by measuring the interaction of electromagnetic radiation in the wavelength range of approximately 780 to 2500 nanometers with the molecular vibrations of a substance. Different chemical bonds absorb light at characteristic wavelengths, creating a unique spectral fingerprint for each compound.

The process typically involves shining NIR light onto a sample and measuring the reflected or transmitted light. The resulting spectrum is then compared to libraries of known spectra using chemometric methods, such as principal component analysis (PCA) or partial least squares regression (PLSR), to identify and quantify components. NIRanalyysillä is a non-destructive and rapid analytical method, making it suitable for a wide range of applications.

Commonly, NIRanalyysillä is employed in industries such as agriculture for analyzing grains, forages, and food products for moisture, protein, and fat content. It is also used in the pharmaceutical industry for quality control of raw materials and finished products, and in the petrochemical industry for identifying and quantifying various chemical compounds. The ease of use and minimal sample preparation required make NIRanalyysillä a valuable tool for routine analysis and process monitoring.
