Basically, it is just a relative amount of each mass fragment. Putting them together into likely molecules is done with a little math.
Explanation:
- A small sample is ionized, usually to cations by loss of an electron.
- The ions are sorted and separated according to their mass and charge.
- The separated ions are then measured, and the results displayed on a chart.
