Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is one of the most powerful and sensitive analytical tools for determining trace and ultra-trace metals in a wide array of complex chemical and biological matrixes.
A series of nine ten-cent coins were also analyzed using ICP-MS to relate the XRF response to metal ion concentrations. A linear correlation between lead concentration to XRF response allowed for quantitation of lead contamination. Greater amounts of lead were seen in coins minted prior to 1900...
