Computers And Computing In FT-IR Spectroscopy
SPIE Proceedings, 1989The state-of-the-art in inexpensive computing for FT-IR spectroscopy is examined. Problems concerning instrument communications, data transportability, networking using personal computers are explored. The use of personal computers in advanced chemometric applications is examined including applications of discriminant analysis for the classification of

FT-IR Spectroscopy in an Industrial Laboratory
Applied Spectroscopy, 1984FT-IR spectroscopy is used widely in many industrial laboratories. In combination with techniques such as gas chromatography, diffuse reflectance, and photoacoustic spectroscopy, it provides a means of tackling certain problems which would be impossible or at least very difficult and time-consuming with the use of dispersive Infrared instrumentation ...

Optical Contact in ATR/FT-IR Spectroscopy
Applied Spectroscopy, 2001Optical contact between an internal reflection element (IRE) and a sample is crucial for obtaining a good spectrum in an attenuated total reflection (ATR) experiment. When an air gap is present between the IRE and the sample, the spectrum severely deteriorates.

FT-IR Emission Spectroscopy and its Applications
Applied Spectroscopy, 1993The practical aspects of infrared emission spectroscopy are reviewed briefly, with emphasis on recent developments and on special problems encountered in measurements of adsorbed species on opaque substrates. A few examples are given for cases when the species of interest give rise to inverted emission bands on the background of substrate emission ...

Reflection Spectroscopy With The FT-IR Microscope
SPIE Proceedings, 1989The FT-IR microscope is a versatile sampling accessory used to record IR spectra in either transmittance or reflectance modes and capable of obtaining data from microscopic sampling areas. Because the FT-IR microscope simplifies the collection of reflectance data it has renewed interest in reflectance spectroscopy.

PVC plastisols decomposition by FT-IR spectroscopy
European Polymer Journal, 1997A specially designed cell, as described in previous papers, has been used to study the dynamic in situ decomposition of PVC plastisols by FT-IR. The FT-IR spectra provides a new point of view into the intricate problem of the effect of the plasticizers (compatibility and concentration) in the PVC decomposition.

Comparison of FT-IR and Raman Spectroscopy
1980Paralleling the evolution of Fourier Transform Infrared Spectroscopy during the 1960’s and 1970’s there have been rapid developments in the area of Raman spectroscopy. The laser serves only in a secondary role for FT-IR spectroscopy, but as a source for excitation it has greatly revolutionized conventional Raman spectroscopy and led to the advent of ...

Depth Profiling by FT-IR Photoacoustic Spectroscopy
1997Adding photoacoustic phase data to photoacoustic magnitude data allows for more complete and more quantitative depth profiling of samples with depth dependent composition. Phase modulation is used here to quantitatively measure layer depths in discretely layered samples.
