Dear Technetters,
I just got a new XRF measuring device which I am very proud of.
Until now I was performing cross sections with poor results for 
very thin coatings.The calibrations which were included in the XRF
device are based on samples starting with 0,40 micrometers gold on
1,5 micrometrs nickel.My range of interest is from 0,07 micrometers
gold to 0.35 .
Could anyone help with information cocerning the following:
Which set of calibration standards is recommended for my appliccation?
How does the plating method affect the results?
Which is the best way to get a corellation between my measurements
and the supplyer's measurements?
Any help or comments are very welcome,even personal experiences .

Gaby
