Title: Calibrating Carbon Coated Standards to Samples with a Gold coat
Post by: Samuel Saltzman on September 25, 2015, 12:40:00 PM
Hi,

Anyone have any good literature on applying carbon coated standards to gold coated unknowns?  Particularly how to quantify the change in x-ray absorption.

Hi Sam,
Both Probe for EPMA and also CalcZAF (our free EPMA utility) can correct for differences in coating between the standard and the unknown for quantification. See here:

The user reference manual that comes with CalcZAF (and PFE) documents what is being done for this "differential" coating correction, but bottom line is: it works!

You can download CalcZAF here for free:
