 Fourier transform spectroscopy - Wikipedia, the free encyclopedia
FTIR of a thin film of ethanol in the liquid phase.
Fourier transform spectroscopy is a measurement technique whereby spectra are collected based on measurements of the temporal coherence of a radiative source, using time-domain measurements of the electromagnetic radiation or other type of radiation.
There are several methods for measuring the temporal coherence of the light, including the continuous wave Michelson or Fourier transform spectrometer and the pulsed Fourier transform spectrograph (which is more sensitive and has a much shorter sampling time than conventional spectroscopic techniques, but is only applicable in a laboratory environment).

 FTIR - Fourier Transform Infrared Spectroscopy
FTIR is most useful for identifying chemicals that are either organic or inorganic.
The term Fourier Transform Infrared Spectroscopy (FTIR) refers to a fairly recent development in the manner in which the data is collected and converted from an interference pattern to a spectrum.
FTIR is perhaps the most powerful tool for identifying types of chemical bonds (functional groups).

 FTIR
FTIR monitors provide both qualitative and quantitative information; which means they identify the compounds present and also calculate the concentration of each.
FTIR monitors are likewise suitable for monitoring toxic chemicals in the vicinity of other Intel facilities, such as those in Chandler, Arizona and Beaverton, Oregon where volatile organic and/or inorganic compounds are released.
FTIR monitors measure only gaseous compounds, and thus cannot measure particulate matter (soot, smoke, dust, etc.) Nonetheless, the FTIR monitors serve as a potent tool for identifying what gaseous organic and inorganic chemicals Intel is releasing and what their concentrations are in the ambient air.

 FTIR   (Site not responding. Last check: 2007-10-12)
The FTIR instrument is a new design of infrared (IR) instrumentation where undispersed light passes through the sample and all the wavelength data is received at the detector simultaneously instead one wavelength at a time as it does in the dispersive instrument.
The objective of the experiment is to identify TWO unknown organic compounds based on the obtained FTIR spectra and the given molecular formulas of the Unknowns.
Obtain a conclusive identification of the unknown by matching the FTIR spectrum of the unknown with those of the known possibilities.

 FTIR (Fourier Transform Infrared) Spectroscopy
During FTIR analysis, a spot on the specimen is subjected to a modulated IR beam.
The resulting FTIR spectral pattern is then analyzed and matched with known signatures of identified materials in the FTIR library.
When the library of FTIR spectral patterns does not provide an acceptable match, individual peaks in the FTIR plot may be used to yield partial information about the specimen.

 FTIR Fourier Transform Infrared Spectroscopy analytical services
FTIR spectroscopy is used primarily for qualitative and quantitative analysis of organic compounds, and also for determining the chemical structure of many inorganics.
This capability allows rapid analysis of micro-samples down to the nanogram level is some cases, making the FTIR unmatched as a problem-solving tool in organic analysis.

 IMB Jena Image Library: Determination of Secondary Structure in Proteins by FTIR Spectroscopy
In FTIR spectroscopy, the light is directed onto the sample of interest, and the intensity is measured using an infrared detector.
The concept of Fourier self deconvolution is based on the assumption, that a spectrum of single bands (each narrow band is characteristic for a secondary structure) is broadened in the liquid or solid state.
Using the parameters a0, a1 and a2, the secondary structure content derived from FTIR spectra is in agreement with X-ray crystallography data.

 FTIR techniques applied to iron gall inked damaged paper
Yet the identification of metallogallic or organic ink via FTIR spectroscopy appears rather difficult, since the main signal is due to the cellulose absorption.
The influence of ink on the FTIR spectrum is also too small to be measured by this technique.
We showed that the presence of iron gall complex can not be detected by FTIR The great differences observed in the spectra should also be attributed to the ink binding substance, and/or to the degradation state of cellulose in the paper.

We have been involved in FTIR spectroscopy in one way or another since its earlier days in the mid-1970s.
We have worked for a few leading manufacturers of FTIR spectrometers over the years (Nicolet, Digilab, Midac) and have provided solutions to some of the leading scientists, universities, and corporations in the world.
We believe the best way to achieve this goal is to work closely with our customers, listening to their needs, and then provide solutions customized by design to meet those needs.

The unit also has accessories allowing multiple paths to be monitored with one FTIR base unit making it very cost effective.
Configurations are also available allowing for more than one path to be monitored with a single base unit reducing installation costs.

 EPA - TTN EMC - FTIR Technology
The FTIR technology shows promise since it has the capability to measure more than 100 of the 189 Hazardous Air Pollutants(HAPs) listed in Title III of the Clean Air Act Amendments of 1990 (CAAA).Upon passage of the CAAA, measurement methods existed for only 40 of theHAPs.
The FTIR has the capability of measuring multiple compounds simultaneously, thus providing an advantage over current measurement methods which measure only one or several HAPs; FTIR Methods can provide a distinct cost advantage since it can be used to replace several traditional methods(cost savings can vary depending on the number of compounds present).
The use of FTIR is being investigated in two modes: extractive FTIR and open path FTIR.
