Romanach and de Haseth [3] have used, in CCC, a how cell for LC-FTIR (liquid chromatography-Fourier transform infrared) spectrometry. The main difflculty is the absorbance of the liquid mobile phase. This problem is exacerbated in EC by low solute-to-solvent ratios in the eluates. On the contrary, CCC leads to a high solute-to-solvent ratio so that it can be used with a very simple interface with a CCC column, without any complex solvent removal procedures. High sample loadings are possible by using the variable path length of the IR detector (from 0.025 to 1.0 mm). [Pg.515]

In Chapter 12, the use of mass spectrometry and Fourier transform infrared spectrometry (FTIR) for GC detection was discussed. Details of these techniques were individually given in Chapters 10 and 12. Much of the discussion presented in Chapter 16 is applicable here. Both liquid chromatography-mass spectrometry (LC-MS) and liquid chromatography-infrared spectrometry (LC-IR) have been adapted to HPLC detection in recent years. [Pg.383]

Analysts. It has been our objective to determine criteria for resin, curative or formulation which would permit prediction of sucess prior to potting tests. Many tests, both chemical and physical in nature, have been executed on commercial resin systems. These have included high pressure liquid chromatography (HPLC), Fourier Transform infrared spectrometry (FTIR), gel permeation chromatography, compressive tensile tests by Instron on resin plaques in air and under various aqueous solutions and heat distortion temperature.

The main spectrometric identification techniques employed are gas chromatography/mass spectrometry (GC/MS) (13), liquid chromatography/tandem mass spectrometry (LC/MS(/MS)) (14), nuclear magnetic resonance (NMR) (11), and/or gas chromatography/Fourier transform infrared spectroscopy (GC/FL1R) (15). Each of these spectrometric techniques provides a spectrum that is characteristic of a chemical. MS and NMR spectra provide (detailed) structural information (like a fingerprint ), whereas an FUR spectrum provides information on functional groups. [Pg.98]

Those areas which have received great attention in Fourier Transform Infrared Spectrometry recently have been the chromatographic infrared spectrometry hybrid systems. This includes gas chromatography-infrared spectrometry and liquid chromatography-infrared spectrometry. Two other areas of current interest are photoacoustic-infrared spectroscopy and the use of infrared spectroscopy to determine impurities in semiconductor materials. [Pg.408]

Detection in SFC can be achieved in the condensed phase using optical detectors similar to those used in liquid chromatography or in the gas phase using detectors similar to those used in gas chromatography. Spectroscopic detectors, such as mass spectrometry and Fourier transform infrared spectroscopy, are relatively easily interfaced to SFC compared to the problems observed with liquid mobile phases (see Chapter 9). The range of available detectors for SFC is considered one of its strengths. [Pg.837]
