Chromatography using a GC-MS (video)

Chromatography is the separation of a mixture of compounds into individual components.
There are three major steps involved with separating and identifying components of a mixture using a GC-MS. They are:
Injecting a sample into the GC inlet
Separating the sample into individual components
Detecting the compounds present in the sample. This is done in the detector. In the video shown below, the detector is a mass spectrometer.
Chromatography using a GC or GC-MS has been described in previous posts:

A GC-MS analytical instrument equipped with an autoinjector is shown in the following video. A sample is automatically injected into the GC inlet and separation and identification of its constituents takes place.
