Fast biomass compositional analysis using Fourier Transform Near-infrared Technique
The objectives of this research were to determine the variation of chemical composition across botanical fractions of cornstover, and to use Fourier Transform Near-infrared (FT-NIR) techniques to qualitatively classify separated cornstover fractions, and develop calibration model for the quantitative analysis of chemical compositions of cornstover. Large variations of biomass chemical compositi...
متن کاملA near infrared technique for non-destructive evaluation
There are many NDE inspection situations where it is not always possible to use traditional methods. For instance, there are situations in which materials are both non-conducting electrically, and non-ferromagnetic, which restricts the testing options. If the use of ultrasound is difficult (for example because of additives, inclusions or air pockets increasing scattering, or because of viscoela...
متن کاملNon-destructive determination of ethanol levels in fermented alcoholic beverages using Fourier transform mid-infrared spectroscopy
BACKGROUND Traditional fermented alcoholic beverages are indigenous to a particular area and are prepared by the local people using an age-old techniques and locally available raw materials. The main objective of this work was the direct determination of ethanol in traditional fermented alcoholic beverages using mid infrared spectroscopy with partial least squares regression, verifying the robu...
متن کاملTechnique for the metrology calibration of a Fourier transform spectrometer.
A method is presented for using a Fourier transform spectrometer (FTS) to calibrate the metrology of a second FTS. This technique is particularly useful when the second FTS is inside a cryostat or otherwise inaccessible.
متن کاملAdvantages of Fourier-Transform Near-Infrared Spectroscopy
Introduction A near-infrared spectrum (12000 – 4000 cm-1) is composed of combination and overtone bands that are related to absorption frequencies in the mid-infrared region. These combination and overtone bands correspond to the frequencies of vibrations between the bonds of the atoms making up the material. Because each different material is a unique combination of atoms, no two compounds pro...
