Determination of Cu, Zn, Ga, Ag, Cd, In, Sn and Tl in Geological Reference Materials and Chondrites by Isotope Dilution ICP‐MS

Geostandards and Geoanalytical Research, Volume 44, Issue 4, Page 733-752, December 2020., 2020
Key Points Mass fractions for eight volatile elements (Cu, Zn, Ga, Ag, Cd, In, Sn and Tl) in 21 geological reference materials by ID‐Q‐ICP‐MS are reported. Target elements were chemically separated with a novel anion‐exchange chromatography. The intermediate precision (2s) of 2–4 replicates was < 4% and results agree with literature data.
