Secondary <strong>Ion</strong> Mass Spectrometry<br />
• Primary ion beam (KeV or MeV) is used to sputter target material<br />
• Secondary ions are analysed in mass spectrometer<br />
• Surface mass spectrometry<br />
• High sensitivity– ppb<br />
• Molecular specificity<br />
• Quantification difficult
