To learn as much as possible about the surface of your samples, it is typical to analyze the samples without any Argon ion milling (as received state).  If you request ion milling at the start, we will do the ion milling to a depth of 20 nm (200 A) or less.  Note:  Ion milling destroys most polymer chemistry and greatly degrades many metal oxides. Ion milling causes differential loss of various elements.
