Preferred Label : Secondary Ion Mass Spectrometry;
NCIt definition : An analytical technique in which a mass spectrometer is used to detect sputtered ionized
atoms (secondary ions) that are ejected from a solid surface after application of
a beam of high energy primary ions.;
Alternative definition : CDISC: An analytical technique in which a mass spectrometer is used to measure the
atomic weight of sputtered ionized atoms (secondary ions) that are ejected from a
solid surface after application of a beam of high energy primary ions.;
