Methods for solid sample preparation and preprocessing of FTIR data were developed to assure Beer-Lambert law compliance and produce a well-conditioned multivariate system. The model was tested using composite samples of zein protein, corn starch and azolectin lipid, and corn samples containing known...
(FTIR).The polymer was then applied to solid phase extraction(SPE) of olivetol from spiked wheat bran samples.From the equilibrium binding experiments,it was showed that MIP had a better recognizability for the template molecule.Scatchard analysis showed that MIP had specific adsorption to olivetol ...
Similar protocol was followed for the preparation of lipid reconstituted ASR for DSC, FTIR, and UV-Vis measurements, except that ASR was expressed using non-isotopically labeled glucose and ammonium chloride. SSNMR detected H/D exchange experiments ...
motion, thus are unlikely to adopt the partial alignment observed in woods using Fourier-Transform Infrared (FTIR) and Raman spectroscopy36,37. In addition, lignin contains both rigid and mobile components (Supplementary Fig.7,8), indicative of the coexistence of aggregated rings and polysaccharide ...
ATR-FTIR can obtain infrared spectra without complex sample preparation (Jung et al., 2018); thus, it has become one of the most commonly used spectrometry technologies in recent years (Giamougiannis et al., 2021, Sharma et al., 2021). A large number (1,272) of different types of ...

The adsorption of CH(D)Cl3 and CHF3 on a series of alkali-exchanged Y-zeolites was studied by 1H- and 23Na-NMR and by FTIR spectroscopy. Several adsorption... E Bosch,S Huber,J Weitkamp,... - 《Physical Chemistry Chemical Physics》 被引量: 73发表: 1999年 加载更多来源...
An accessory for an FTIR spectrometer comprises fiber-optic cables connected to a framework within which two mirrors are housed. The mirrors, which are preferably off-axis parabolas, are positionable with respect to each other and with respect to the ends of the fiber-optic cables. The beam fr...
(FTIR) characterization from 400 to 950 cm−1of each PhNPs was conducted, as shown in Fig.2a. Upon incorporation of NaTFSI/PC into PVDF-HFP, the intensity of the crystalline phase (α-phase) of PVDF-HFP, which is located at 980 cm−1(—CF2and —CC symmetric stretching), 796...
FTIR spectra were recorded on a Fourier transform infrared spectroscopy (Bruker EQUINOX55, Germany) to analyze the functional groups of the solid acid. The thermal stability of the solid acid was characterized with a DTG-60H/DSC-60 ther- mogravimetric analyzer (TGA, Shimadzu Co., Japan). The...
