Leaks and Obstructions: Troubleshooting Common Problems Close to the Point of Sample Injection ...

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 ...

Gas chromatography (GC) is best suited for the analysis of volatile or gaseous compounds. Ideally, a liquid sample or its vapor would be directly introduced into the injection port. But to analyze the ...

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 ...

A, Syringe injection into hot vaporizing chambers. Introduction -- Syringes -- Evaporation inside the needle -- How much is really injected? -- Syringe needle handling minimizing discrimination -- ...

Miniaturized gas chromatography (µGC) systems hold potential for the rapid analysis of volatile organic compounds (VOCs) in an extremely compact and low-power enabled platform. Here, we utilize ...

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) ...

In this case study of amines, the authors discuss several parameters to be considered in developing a headspace GC method. Headspace gas chromatography (GC) has been used since the 1980s, but only ...

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 ...
