Abstract
The invention includes a method of detecting impurities in a metal-containing article. A portion of metal material is removed from a metal article and is solubilized in an acid or base-comprising liquid to produce a liquid sample. The liquid sample is subjected to an incident laser beam and light scattered from the sample is detected. The invention includes a method of analyzing a physical vapor deposition target material. A portion of target material is removed from the target and is rinsed with an acid-comprising solution. The portion of target material is dissolved to produce a liquid sample. The sample is subjected to an incident laser beam and scatter of the laser beam is detected to determine the number of particles present in the sample within a particular size range.
