How Does a GC-MS Work?
Gas chromatography (GC) and mass spectrometry (MS) are two instrumental methods of scientific analysis. Used concurrently, a GC-MS instrument will separate out the individual components of a mixture in order to tell you:
- What a substance is composed of
- How much of each of the components is present
The Gas Chromatograph (GC)
A gas chromatograph (GC) comprises of a heated inlet port, an oven, and a fused silica column (essentially a coiled glass tube) which has been coated with a special material called the stationary phase.
The GC produces a graph called a chromatogram, where each separated substance is represented by a peak. The number of peaks shows the number of separated compounds in the sample. The position of each peak shows the retention time for each compound.
