Complementary Gas Chromatography - Mass Spectroscopy

The use of GC-MS grew rapidly during the 1970s as discussed by Sharleford and 

There are several major suppliers of equipment for this technique including Finnigan MAT [4-26], Thermoelectron, Perkin Elmer Corp, Shimadzu Corp and Varian Instruments.

Complementary Thermogravimetry, Gas chromatography-Mass Spectroscopy and Fourier-Transform-Infrared Spectroscopy... 

Analysis of trace compounds. All fractions were checked by capillary gas chromatography (GC) with FID and sulfiir specific detection (flame photometric detector, FPD ThermoQuest CE, Egelsbach). Subsequently the different fractions were analyzed by capillary gas chromatography-mass spectrometry (GC-MS). Specific unknowns were enriched by preparative multidimensional gas chromatography (MDGC). For further structure elucidation complementary analyses using GC-MS and capillary gas chromatography-Fourier transform infrared spectroscopy (GC-FTIR) as well as H-NMR were applied. All new compounds have been synthesized and characterized by GC-olfactometry (GC-0). 

The Coast Guard has selected two complementary methods for use by its Central Oil Identification Laboratory (COIL), which is an operational unit devoted full time to oil spill fingerprinting, namely LTL and HPLC. Other methods that have been used are atomic absorption spectroscopy (AA), emission spectroscopy (ES), X-ray fluorescence (XRF), gas chromatography-mass spectrometry (GC-MS), mass spectrometry (MS), and limited wet methods of analysis (23). 

During investigation of a new material it is unlikely that any single thermal analysis technique will provide all the information required to understand its behavior. Complementary information is usually needed, which may be from another simultaneous thermal technique such as thermogravimetric-differential scanning calorimetric-mass spectrometry (TG-DSC-MS), gas chromatography (TG-GC, or DSG-GG), or spectroscopic methods such as IR spectroscopy or X-ray photoelectron spectroscopy (XPS). 

Some aromatic amines resulting from the reduction of azo dyes have been identified by FTIR (Franciscon et al. 2009 Pielesz 1999). However, FTIR by itself is not always sufficient, so Mass spectroscopy. Gas and/or Liquid chromatography are techniques currently being used as complementary ones for compounds identification. 

Chapters 3-8 cover the complementary methods, based on the combination of mass spectroscopy with various chromatographic techniques such as high-performance liquid chromatography, gas chromatography and supercritical fluid chromatography. 

Whilst pyrolysis-gas chromatography (Py-GC) is a very important analytical tool for the elucidation of polymer structure, the technique becomes even more useful when it is coupled with complementary techniques such as infrared (IR) spectroscopy and more recently mass spectroscopy (MS) (see Chapter 3). These techniques, particularly MS can be used to provide unequivocal identification of volatile pyrolysis products produced on pyrolysis or of individual pyrolysis products separated by GC. 

Mass spectrometry is included also in section 11 when used as a standalone detector for identifying the eluents of gas and liquid chromatography column separations (as in GC-MS and LC-MS). As with the other methods (IR, UV-visible, NMR spectroscopy and XRD), mass spectrometry is a complementary technique used for the characterization of organic compounds and various applications have been mentioned. ...
