METAL SPECIATION - CAS Lab

Metal speciation is the determination of the form(s) of an element in a sample This might be limited to speciating by valence of an inorganic form (eg hexavalent chromium vs trivalent chromium vs total chromium), or it might include speciating by valence and/or combined form(s) (eg elemental mercury vs mercuric ion vs methyl mercuric ion)...
