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 Star Trek, Mr. Spock’s hand-held tricorder can instantly tell what something is made of. We don’t have tricorders yet, but we’re getting close. Portable devices just a little too big to hold in one ...

Gas chromatography is an innovative technique that uses an inert carrier gas for separating and quantitating vaporized compounds. It is based on principles similar to column permeation chromatography, ...

When gas chromatography (GC) is used to separate a complex mixture, selection of the appropriate carrier gas and the optimum source for the carrier gas in GC are critical decisions for the laboratory ...

The sludge left over from refining crude oil is one of the most chemically complicated and environmentally harmful types of industrial waste. Studies often report how much of the ...

(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 ...

Deep learning can speed up the analysis of gas chromatography data, researchers report. Because this type of analysis is used in a variety of ways, the new method will have a major impact on quality, ...

Chiral gas chromatography–mass spectrometry (GC–MS) shows how heat and storage alter linalool in blueberry juice. Blueberry juice is loved for its unique taste and its health benefits but heating it ...

We report the design, fabrication and characterization of a microelectromechanical systems (MEMS) flow control device for gas chromatography (GC) with the capability of sustaining high-temperature ...

Gas chromatography is an innovative approach to separating and quantitating vaporized compounds through the use of an inert carrier gas. Gas chromatography functions according to similar principles as ...

Analysts interested in quantifying volatile organic compounds like disinfection byproducts in liquid samples should consider using the gas chromatography system. There are two gas chromatography (GC) ...
