The metals are usually analyzed by Atomic Absorption Spectroscopy, or in
some cases Atomic Emission Spectroscopy. I actually performed an oil
analysis once as part of a chemical research project, and I looked up all
this stuff. The metals are dissolved out of the oil with a mixture of
strong acids (some violent reactions occur here!), extracted into an
aqueous solution, and then the metal ions are detected spectroscopically.
