Key Points

Comparison of Two Methods for Determination of Rhenium and Platinum-Group Elements in Meteorites Using On-Line and Off-Line Matrix Separation Modes Issue , Key Points

  • PEEK tubing has been observed to adsorb Pd and Pt ions, resulting in significantly reduced recoveries of Pd and Pt elements.
  • HPA-S provides a more effective dissolution for meteorite samples than Carius tube digestion, resulting in higher mass fractions for PGE.
  • On-line cation measurement provides full control of spectral interferences such as Cd, Hg, Zr, etc.
