[Ifeffit] Calculation of metal concentration (and hence density) from Edge Jump

[pushkar shejwalkar]

Dear All,
    First of all, is it possible to calculate the concentration of metal
(loading, therefore) from just the edge jump? Is there a simpler equation
like knowing the Flux values or some basic instrumental information we can
calculate the concentration term using Io and It values of beamline (the
simplest form of Beer-lambert law)? if so what formula should we use.
I searched in the mailing list archive and have found one such archive but
it discusses how to use calculation to find out how much sample would be
needed to get the edge jump. I am rather interested in the reverse way. I
have an experimental edge jump and want to calculate (if possible with as
much accuracy as possible) the concentration of metal. I know with only
edge jump it will be difficult and XRF will be a better and more reliable
way. But for better understanding and cross checking between different
samples, I wish to do such calculations.
Can anyone guide me to the right direction and equations to do such
calculations?
Thank you all in advance
Warmest regards
Pushkar
