Precious Metals

The mining industry is constantly in search of precious metals. Rock samples require grinding and then digestion by the appropriate Digestion System
(See Method Development Guide, page 18). However, precious metals are found in limited quantities versus other metals in the same sample. Hence,
their analysis may be more difficult. The PM series of DigiSEP Cartridges will retain and concentrate precious metals. The metals can then be eluted
and analyzed at higher concentrations in the absence of interferences.
