in Coal Fly Ash. The project was accepted by APS and we will conduct

Dear Mengling,
The basic issues are: will there be enough Tl fluorescence counts in
the detector, and will you be able to see a decent edge.From you
spreadsheet of concentrations, the elements that stand out are: Fe
and to a lesser extent Zn, and Pb.
The Fe and Zn will dominate the

Hi Kleper,
That's not Pt foil data. You got that data from the

Dear Matt,
this is very good introduction for fluorescence measurements on diluted
samples... Like a tutorial...
I just want to add small comments: as I understood the sample is an ash,
so maybe will be possible to condense it, e.g. press it into the pellet.
If there will be no possible to

Sorry. I don't know how I missed that.

Is ATOMS available as an executable program anymore? I can't seem to find
a download for it on the IFEFFIT site. Is the idea to only use the web

I stopped supporting a stand-alone version of atoms for a while,
Thanks for all the response! They are all very helpful!
Just want to make sure that I get the information right and a few follow-up
questions:
1. I'd better contact the beamline engineer to ask for the sensitivity for
Tl.
2. Fe fluorescence interference could be decreased by adding a few layer
Thank you so much!
This is the first time I tried to use ifeffit mailing list. I would have
never expected so many responses from so many scientists. I wish one day I
could be able to contribute back to this great scientific community as well!
Thanks again!

Dear Mengling,
As Caroline Peacock from Leeds has successfully done Tl L3 microXAFS on some
samples on I18 at diamond, I Have a little experience.
She has a paper on the work currently in review.
As Matt says if you have Pb in the sample your data is limited to just under
350 eV (10 k). Micro
