Secondary ion mass spectrometry (SIMS) is a technique used to analyze compositions of thin films and surfaces by using a focused primary ion beam to sputter the surface of a sample and analyze the ejected secondary ions. SIMS is a qualitative technique nominally but, if combined with standards, can be considered a quantitative technique.

How does mass spectrometry work? In MS analysis, the mass-to-charge ratio of ions is measured. This is done by ionizing a sample, separating the ions or fragments according to their mass-to-charge (m/e) ratio, and then detecting these charged particles by a detector/analyzer where molecular weight is measured.Figure 4.4.1 4.4. 1: Time-of-Flight Mass Spectrometer. In the source of a TOF analyzer, a packet of ions is formed by a very fast (ns) ionization pulse.
