Solution and laser ablation MC-ICP-MS lead isotope analysis of gold

Solution and laser ablation MC-ICP-MS lead isotope analysis of gold

A new approach is presented for the analysis of lead isotopes in gold using solution and laser ablation multi-collector inductively-coupled plasma mass-spectrometry (MC-ICP-MS). Repeat analyses of two gold reference materials (RAuGP3: 34.1 plus or minus 0.5 ppm Pb and RAuGP5: 129 plus or minus 4 ppm...

Zusammenfassung:A new approach is presented for the analysis of lead isotopes in gold using solution and laser ablation multi-collector inductively-coupled plasma mass-spectrometry (MC-ICP-MS). Repeat analyses of two gold reference materials (RAuGP3: 34.1 plus or minus 0.5 ppm Pb and RAuGP5: 129 plus or minus 4 ppm Pb, from SPEX CertiPrep Ltd) yield an external reproducibility of
