All,

I know nothing about the JEOL software and haven't looked at Julien's script, but technically one should include the calculated CO2 in the matrix correction, because adding these unanalyzed elements does change the matrix correction physics, often significantly.

I think I'll write up a short post on this issue on the Probe Software User Forum.

I personally do not use the JEOL software for calculating the CO2 content. During the analysis, I simply specify a fixed amount (44% for calcite, 52% for magnesite, 38% for Fe-rich one, or an intermediate value), and recalculate the CO2 content offline using my little web-based script or an XL spreadsheet.

My own online tool is available here, you can simply copy & paste data from excel (without the column “total”): http://ethz.geoloweb.ch/index.php?page=mineral_formula&reset=true

Cheers,

Julien

Hi all
I am running carbonates and having issues wrapping my head around the JEOL software.
I have set up the analyses as oxides, with CO2 added. In the element condition option under CAL I have the option to define how many CO2 are added for a group of specified elements and I have set up so (as I understand things) it should add 1 CO2 for 1 Ca, 1 Mg and 1 Fe. However, the software only adds CO2 for the first element on the list –  So I can run a calcite and it works perfectly, but if I run a dolomite it adds CO2 for Ca but not Mg.
Is this a software is or am I just doing something dumb!
Cheers
Tod
PS I am running a JEOL8200, with software from 2011 (VO1.55)
