WebA mass spectrometer (MS) is commonly used as a GC detector. The MS will break each separated compound coming from the GC into ionised fragments. To do this, a high energy beam of electrons is passed through the sample molecule to produce electrically charged particles or ions. These fragments can be large or small pieces of the original molecule.
