Nirs machine
WebbLa spectroscopie NIR est une méthode qui utilise la région proche infrarouge du spectre électromagnétique (d'environ 700 à 2 500 nanomètres). En mesurant la lumière diffusée sur et à travers un échantillon, les spectres de réflectance NIR peuvent être utilisés pour déterminer rapidement les propriétés d'un matériau sans modifier l'échantillon. Webb30 nov. 2024 · There are two general categories of NIR devices: filter-based and full-spectrum. Filter-based devices are particularly well suited to most types of processing, according to Bogart. NIR filter-based equipment blocks visible light and allows only certain wavelengths of IR light to enter the device.

WebbHow does a NIR machine work? In NIR spectroscopy, the unknown substance is illuminated with a broad-spectrum (many wavelengths or frequencies) of near infrared light, which can be absorbed, transmitted, reflected or scattered by the sample of interest. The illumination is typically in the wavelength range of 0.8 to 2.5 microns (800 to 2500nm). Webb19 feb. 2024 · The NIR spectra of the culture samples were automatically recorded using the 96-well microplates (20 μL) in the microplate reader. The microplate reader allows collecting the spectra ranging from 200 to 1000 nm. In this study, the near-infrared range between 750 and 1000 nm (2-nm resolution) was acquired for each sample.
