207Pb/206Pb fractionation correction in UcomPbine

Chao

Hello,

In analytical sessions where the 207Pb/206Pb fractionation is noticeable, i think the strategy for the data reduction should be:

Determine a 207Pb/206Pb normalization factor from a homogeneous reference material, like NIST610
Apply the 207Pb/206Pb normalization factor to the standard (which has varying amount of Pbc) offline
Import the modified standard data and unknowns into Iolite
Let UcomPbine do the 207-correction, downhole correction, and Pb/U normalization
Exported data shall have to be multiplied by the 207Pb/206Pb normalization factor before pulling a disconcordia line

Is there a modified UcomPbine DRS does that? 🙂
I am running V3.71.

Thanks!

Joe

This is possible in the iolite 4 version of UcomPbine starting around version 4.5.5, I think. There is no version for iolite 3 doing this that I am aware of, but it is open source, so you can change it if you wish.

All the best,

Chao

Joe Great! Thank you.
