The objective of this study was to produce a fast, accurate, and precise method for analyzing terpenes in hemp using headspace/gas chromatography/mass spectrometry. Modern interest in terpenes and ...

In this article, Thermo Fisher Scientific compares on-line gas chromatography and mass spectrometry, touching upon the benefits, drawbacks and situational use of each.

In gas chromatography (GC) the paint sample is placed in a solution. This solution is then injected into a stream of gas, usually helium . This gas in turn is forced through a thin heated tube.

Comprehensive two-dimensional gas chromatography (GC×GC) integrated with mass spectrometry represents a state-of-the-art analytical technique that significantly enhances the separation and ...
