Comparing a Near IR spectrometer (diffuse reflectance) to a Raman/FT-Raman spectrometer In a previous article, a near IR spectrometer operating in diffuse reflectance geometry was compared with a FTIR/FT-NIR spectrometer. In this article the attention is turned to comparing a near IR spectrometer to a Raman/FT-Raman spectrometer. Each one will have its advantages and disadvantages …

Comparing the NIR spectroscopic method with FTIR/FT-NIR The goal of this article is to compare the near IR spectroscopic technique with FTIR and FT-NIR methods. Molecular spectroscopy is the study of interaction of Electromagnetic waves with matter. Molecular bonds are capable of rotation and vibration which include bending and stretching. When an electromagnetic wave of …

Different field applications for portable near-IR spectrometers (Diffuse reflection) Near-IR spectroscopy was first discovered by William Herschel in 1800 when he observed that the region outside the dispersed visible spectrum near the red wavelength increased the temperature of a thermometer. Later he verified that the invisible rays also follow the properties of waves such as …
