(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 ...

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.

Gas chromatography is a common chromatography technique used to separate and analyze volatile chemical compounds which do not decompose. It is typically used to separate different compounds within a ...

During one-dimensional gas chromatographic (1D-GC) analyses of complex biological, environmental, or petrochemical samples, the outcome is often a chromatogram that has a huge portion of unresolved ...

This is the Best of the Week. Voices from the Analytical Front Line: Bingchuan Wei on Chromatography in 2026 In the year 2026, chromatography is undergoing a series of advancements and challenges.

Chromatography is a proven method used to separate complex samples into their constituents, and it is undisputedly the most important procedure for isolating and purifying chemicals. It is classified ...

What is gas chromatography and liquid chromatography? Gas chromatography is a chromatographic method that uses gas as a mobile phase. The sample flows through the gas system and is gasified before ...

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 ...

Chromatography is a process for separating components of a mixture for analysis. This is a component of our small molecule analysis testing and plays a critical part in identifying and quantifying ...

Counterfeit or low-quality products – such as olive oil made from dyed rape-seed oil – are often difficult or impossible to identify at a glance. A mobile gas chromatography sensor system is now being ...

Gas chromatography was discovered by Russian-Italian botanist, Mikhail Semyonovich Tsvet, in the early 1900s. The separation technique is used to first split the chemical components of a mixture, then ...
