Identification of arsenolipids with GC/MS

Talanta, 2009
Arsenic-containing hydrocarbons have recently been reported as natural constituents of fish oil. We report a simple method for determining these compounds by GC/MS. Application of the methodology will delineate the distribution of these novel arsenic compounds in foods, and facilitate an assessment of the toxicological implications.

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.

Flying High with Sensitivity and Selectivity: GC–MS to GC–MS/MS

LCGC North America, 2021
Mass spectrometry (MS), often termed mass selective detection, is the most powerful detector available for gas chromatography (GC). Multidimensional mass spectrometry (MS/MS) takes mass selective detection to another level on benchtop systems, offering both universal and selective detection along with low detection limits.

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-

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

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 ...

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 ...
