Static Secondary-ion Mass Spectrometry - Spectrum
... The mass spectrum of the secondary ions emitted from the bombarded surface during SSIMS provides direct information of not only chemical composition ... This is because the mass spectrum includes cluster ions as well as elemental ions ... These cluster ions reflect the surface chemistry in a detailed way ...
Arsenate - Ions
... it exists as arsenic acid, H3AsO4 in weakly acidic conditions it exists as dihydrogen arsenate ion, H2AsO4− in weakly basic conditions it exists as hydrogen ...
Cementation (metallurgy)
... is a type of precipitation, a heterogeneous process in which ions are reduced to zero valence at a solid metallic interface ... Copper ions in solution, often from an ore leaching process, are precipitated out of solution in the presence on solid iron ... The iron oxidizes, and the copper ions are reduced through the transfer of electrons ...
Static Secondary-ion Mass Spectrometry - Mechanism
... Most energy of the primary ions is dissipated into the near surface region of the solid by a series of binary collisions ... neutral species, atoms, and molecules atomic and cluster ions from the surface ... In SIMS it is these secondary ions which are detected and analyzed by a mass spectrometer to produce a mass spectrum of a surface for a detailed chemical analysis of the surface or the solid ...
Low-energy Ion Scattering - Experimental Setup
... LEIS systems consist of the following Ion Gun, used to direct a beam of ions at a target sample ... An electron ionization ion source is typically used to ionize noble gas atoms such as He, Ne or Ar, while heating of wafers containing alkali atoms is used to create an alkali ... The ions thus created hold a positive charge, typically +1, due to the ejection of electrons from the atoms ...
