Standardizing GC–MS metabolomics

Journal of Chromatography B, 2008
Metabolomics being the most recently introduced "omic" analytical platform is currently at its development phase. For the metabolomics to be broadly deployed to biological and clinical research and practice, issues regarding data validation and reproducibility need to be resolved.

Archaeological wood characterisation by PY/GC/MS, GC/MS, NMR and GPC techniques

Microchemical Journal, 2007
Abstract The chemical characterisation of waterlogged archaeological wood is of paramount importance in terms of understanding not only the degradation processes of wood in artistic and archaeological objects but also the development of consolidation and conservation procedures.

Untargeted GC-MS Metabolomics

2018
Untargeted metabolomics refers to the high-throughput analysis of the metabolic state of a biological system (e.g., tissue, biological fluid, cell culture) based on the concentration profile of all measurable free low molecular weight metabolites. Gas chromatography-mass spectrometry (GC-MS), being a highly sensitive and high-throughput analytical ...

Exploring Metabolome with GC/MS

2013
Abstract The rapidly expanding field of metabolomics has been driven by major advances in analytical tools such as mass spectrometry and the corresponding hyphenated methods such as gas chromatography (GC–MS) but also in chemometrics and bioinformatics. The metabolomic field has been mainly developed in plant sciences and GC/MS was applied very early

GC-MS and GC-MS-MS analysis of a complex essential oil

Chromatographia, 1988
The alcoholic portion of avetiver oil (Bourbon), the gas chromatogram of which shows more than 100 components, was analyzed by combined GC-MS with different ionization methods. This enabled us to identify major components. The specificity of the method was improved by using combined gas chromatography-tandem mass spectrometry in the collision-activated-

Differentiation of the six dimethoxypyrovalerone regioisomers: GC-MS, GC-MS/MS and GC-IR

Talanta, 2017
Multiple and complementary analytical methods are often necessary for the identification of a specific compound from a series of closely related structural isomers. Gas chromatography-mass spectrometry (GC-MS), gas chromatography-product ion mass spectrometry (GC-MS/MS) and gas chromatography-infrared spectroscopy (GC-IR) were used to differentiate ...

GC-MS of Auxins

1986
The frequent lack of correlation between endogenous levels of auxins and selected physiological processes which has often been reported in the literature suggests the conclusion that such correlations do not often exist. However, from a critical evaluation of the methods used for such studies, it is apparent that most of the qualitative and ...
