G-SIMS is an easy-to-use method that considerably simplifies complex static secondary ion mass spectrometry (SSIMS) spectra into spectra with only those ions that are highly characteristic of the surface.

If the incident beam is to reach the sample, and the emitted electrons are to be detected, then their mean free paths in the region of the sample must be greater than the physical dimensions of the apparatus involved, otherwise scattering will distort the outcome
