Dear Iolite Team,
Recently the paper “Community-Derived Standards for LA-ICP-MS U-(Th-)Pb Geochronology – Uncertainty Propagation, Age Interpretation and Data Reporting” was published, suggesting:
(8) Use ID-TIMS reference ratios (with/without common Pb or 230Th correction as appropriate to the LA data being normalised) specific to the isotope ratio of interest, not an assumed-age equivalent calculated ratio. For most current practices, this entails using ratiospecific reference values without common Pb or 230Th corrections from non-chemically abraded materials.
In Table 2 there are reference ratios given with and without initial Pb.
Do you plan to update the standard files distributed with Iolite, and send them to customers? Or do users of Iolite have to be responsible to use the correct reference values?
