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 ...

(GC) is an analytical technique used to separate and detect the chemical components of a sample mixture to determine their presence or absence and/or quantities. These chemical components are usually ...

LPG is bought, sold and distributed based on composition. The balance of propane, butane and related hydrocarbons determines ...

A novel workflow combining comprehensive two-dimensional gas chromatography (GC×GC) with computer vision (CV) was developed to analyze the complex volatile profiles of coffee. By generating composite ...

Brewers producing alcohol-free and low-alcohol drinks often face a simple challenge: measuring alcohol accurately at very low ...

In this article, we take a look at what gas chromatography is, how it works and how to interpret output data. Its combination with mass spectrometry and the use of multiple dimensions are considered.

In the food industry, food product analysis is crucial for QC purposes, authenticity of products and materials, and brand awareness. The combination of GC and high-resolution TOFMS provides reliable ...

To systematically trace the evolution of key aroma compounds from tobacco leaves to smoke, researchers developed a combined strategy of stirred barrel sorption extraction (SBSE), pyrolysis (PY), and ...

Gas chromatography–ion mobility spectrometry (GC–IMS) is a recent technique applied to food flavor analysis – including the evaluation of food freshness, processing of food products, and changes in ...

Researchers have figured out how to use deep learning to speed up the analysis of gas chromatographic data. Because this type of analysis is used in many parts of society, the new method will have a ...
