Chances are good that most of us will go through life without ever having to perform gas chromatography ... Those hold the detectors, an MQ-2 gas sensor module, and a thermal conductivity sensor ...

Novel multidimensional separations such as comprehensive two-dimensional gas chromatography (GC×GC) or comprehensive two-dimensional liquid chromatography (LC×LC) allow us to be more successful ...

Owing to the complexity of food matrices, two-dimensional gas chromatography is a more powerful analytical tool to study food samples as a result of its increased ability to separate compounds.

An international research team used two-dimensional gas chromatography time-of-flight mass spectrometry to characterise the odours that create this smell of death: volatile organic compounds (VOCs).
