The position of the peaks on the x-axis indicates the mass of the particles; the peak heights indicate the relative abundance of the particles.
the range ions separated according to their mass; the data output from the GCMS
a distribution of ions as shown by a mass spectrograph or a mass spectrometer
Characteristic fingerprint of a substance, which makes its identification possible.
