MOISTURE MEASUREMENT BY FT-IR-SPECTROSCOPY [PDF]
Drying Technology, 1994 ABSTRACT This contribution reports on the use of a FT-IR-spectrometer for measuring concentrations during the drying of thin films of Polyvinyl acetate (PVAc) and Methanol. Calibration was carried out by differential weighing. The spectra were taken in transmission mode while dried air was blown over the liquid films. The obtained accuracy was +/− (5% +

Characterization and Identification of Micro-Organisms by FT-IR Spectroscopy and FT-IR Microscopy
1994A large series of physical techniques has been tested for the characterization of microbial cells. These techniques include gas chromatographic (GC) and high-performance liquid chromatographic (HPLC) techniques, gel electrophoresis, pyrolysis mass spectroscopy, fluorescence and chemiluminescence techniques, flow cytometry, impedance measurements ...

FT-IR spectroscopy in catalysis
Acta Physica Hungarica, 1987Supported metal catalysts are opaque to infrared rotation generally below 1200 cm−1 thereby preventing all the very important vibrations involving surface-adsorbate or “metal-ligand” motions from being observed by the conventional transmission technique. The possible methods which do not suffer from these limitations are summarized in this paper.

Analytical Applications Of FT-IR
SPIE Proceedings, 1985Kansas State University, Dept. of Chemistry, Willard Hall Manhattan, KS 66502 USAFourier Transform atomic emission spectroscopy is well suited to the determination of nonmetals in the red to near infrared region from 7,900 to 15,800 cm (1). The speed of Fourier Transform spectroscopy allows full spectrum monitoring of transient atomic emissions on a ...

SPIE Proceedings, 1985
The last decade has been a period of astonishing growth and vigor for FT-IR spectroscopy. The first International Conference on Fourier Transform Spectroscopy held in Aspen, Colorado, in 1970, described new instrumentation using Michelson interferometers that had been developed in response to problems in astro-physics, where faster acquisition of data ...

Studies on Organometallic Compounds by FT-IR
Spectroscopy Letters, 1995Abstracts The different substituents of N ‐ methylferrocene of aniline compounds were investigated by FT‐IR spectrometer. On the basis of their IR data , the intra‐ and intermolecular hydrogen bonds between the hydrogen on nitrogen and ferrocenyl as well as benzene ring in molecules and benzene as solvent are discussed in solution of which CCl4 ...

Perhaps the most widely accepted model of ionomer superstructure is the multiplet-cluster concept advanced by Eisenberg [1,2]. This framework has dominated the interpretation of many vibrational spectroscopic studies to the extent that specific infrared bands and Raman lines have been separately assigned to multiplets or clusters.

Analysis of Gasolines by FT-IR Spectroscopy
Analytical Chemistry, 1996An experimental and computational protocol was established for the simultaneous determination of several key gasoline properties from a single Fourier transform infrared (FT-IR) spectrum. The study has shown that midband FT-IR spectroscopy combined with multivariate calibration analysis is a versatile, efficient, and accurate technique for the ...

Sample Analysis through the use of Centrifugal-Vacuum FT-IR (CV/FT-IR)
Applied Spectroscopy, 1989Sample preparation is currently considered an important bottleneck in the analysis of large numbers of samples by FT-IR spectroscopy. For aqueous or alcohol solutions, because of the very strong solvent absorptions over large regions of the infrared spectrum, extraction of the analyte from solution is often necessary prior to measurement of the ...

IR spectroscopy is one of the absorption spectroscopies. As found in a UV-vis spectrometer, IR spectrometers were also developed on the same concept of a UV-vis spectrometer involving a dispersive optical element represented by a prism or a diffraction grating.
