A method has been developed for chemically imaging a buried organic interface of thickness similar to that of a biological conditioning film. Using an ion beam to form a sputter crater, elemental analysis of the edge of the crater is performed using Auger Electron Spectroscopy (AES) and chemical imaging of the edge is performed by Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS). The crater edge that is formed due to the ...
