Explanation:
Detailed explanation-1: -The secondary ion mass spectrometry (SIMS) analysis is destructive technique (sacrifices the surface particles that are analyzed by the mass spectrometer) for analyzing the mass/charge ratio of ionized particles produced from the sample upon bombardment of an energetic (25 keV) primary ion beam (Bi+, Cs+, C60+).
Detailed explanation-2: -Mass spectrometry (MS) is an analytical technique that separates ionized particles such as atoms, molecules, and clusters by using differences in the ratios of their charges to their respective masses (mass/charge; m/z), and can be used to determine the molecular weight of the particles.
