Combination gas chromatography‐mass spectrometry

Journal of the American Oil Chemists' Society, 1967
AbstractThe direct combination of gas‐liquid chromatography with mass spectrometry represents one of the most powerful techniques available for the analysis of complex mixtures of lipids. Principal advantages are the extremely small amounts of material required, the relative speed of analysis, and the wealth of molecular structural information ...

Chromatography, Mass Spectrometry

Chemical & Engineering News Archive, 1997
Even though more high-performance liquid chromatography (HPLQ) instruments are in use than are gas chromatography (GQ) units, GC is much more likely to be paired with mass spectrometry (MS) than is liquid chromatography (LC), according to the 1997 Analytical Instrument End User Study conducted by K. C. Associates, Wilmington, Del.

Integrated gas chromatography-mass spectrometry

Quarterly Reviews of Biophysics, 1973
Mass spectrometric analysis of organic compounds was in the early 1950s done mostly for quantitative determination of petroleum products. The use of the mass spectrometer for qualitative analysis of solid organic material samples was shown by O'Neil & Wier (1951) and since then a continuous increase in mass spectrometric studies of different ...

Supercritical Fluid Chromatography/ Mass Spectrometry

1992
The field of supercritical fluid chromatography (SFC) has experienced a phenomenal growth during the decade of the 1980s, both in terms of publications and practitioners. A noteworthy observation is that the early publications in capillary SFC [1–3] were quickly followed by descriptions of capillary SFC/mass spectrometry (SFC/MS) [4, 5].

Gas chromatography-mass spectrometry

1982
The complexity and wide range of organic acids present in urine, and other biological fluids, makes their quantification and positive identification a difficult problem. Although chromatographic characteristics of individual compounds, such as retention data on gas, liquid and thin-layer chromatography, are extremely useful indicators of probable ...
