Counterfeit or low-quality products—such as olive oil made from dyed rapeseed oil—are often difficult or impossible to ...

Gas chromatography (GC) is used for the analytical separation of volatile substances in the gaseous phase. This chromatographic technique is widely used in various fields of research and industrial ...

One-dimensional gas chromatographic (1D-GC) analyses of complex environmental, petrochemical, or biological samples often result in a chromatogram with a large portion of unresolved components. Mass ...

This paper reports a complete micro gas chromatography (μGC) system in which all the components are lithographically microfabricated and electronically interfaced. The components include a ...

Chances are good that most of us will go through life without ever having to perform gas chromatography, and if we do have the occasion to do so, it’ll likely be on a professional basis using a ...

Fraunhofer's innovative mobile gas chromatography system allows quick detection of volatile organic compounds, crucial for ...

Gas chromatography carries out the quantitative analysis and peculiar smell testing for residual solvent on food packaging cases after printing. It also tests the pureness and quality of organic ...

Fraunhofer researchers are developing a portable gas chromatography sensor system that enables rapid, on-site detection of counterfeit foods and contaminated materials without the need for laboratory ...

Gas chromatography is used to separate the components of a sample and provide a spectral signature for it. The procedure involves injecting the sample into the injection port of the gas chromatography ...

Equipment for gas chromatography, liquid chromatography and mass spectrometry is complex, with multiple subsystems that control the flow of sample analyte, carrier gas and solvent fluids. The ...
