Microbiological characterizations by FT-IR spectroscopy
Nature, 1991Infrared signals of microorganisms are highly specific fingerprint-like patterns that can be used for probing the identity of microorganisms. The simplicity and versatility of Fourier-transform infrared spectroscopy (FT-IR) makes it a versatile technique for rapid differentiation, classification, identification and large-scale screening at the ...

Topical Protectant Evaluation by FT-IR Spectroscopy
Applied Spectroscopy, 1989A unique analytical method for evaluating the effectiveness of topical protectants against penetration by chemical agents has been developed with the use of FT-IR and the horizontal attenuated total reflectance (ATR) accessory. A template was designed which allowed a uniform-thickness layer of topical protectant to be applied to the surface of the ATR

Surface Analysis with FT-IR Emission Spectroscopy
Applied Spectroscopy, 1992The technique of infrared emission spectroscopy (IRES) is reviewed and further examined in this study as a surface analysis tool. A system has been designed which allows simultaneous kinetic and in situ infrared emission analysis of catalyst surfaces. IRES spectra of several gas mixture/solid systems are obtained in order to examine sample preparation

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 ...

MOISTURE MEASUREMENT BY FT-IR-SPECTROSCOPY
Drying Technology, 1994ABSTRACT 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% +

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.
