Preshant,
You might contact Dr. Chris Hunt of the NPL in the UK.  He has studied the 
accuracy of the different XRF technologies.  You can read some of his work 
here.

[TN] XRF equipment suggestions






I am researching XRF equipment for measuring gold plating thickness 
and lead content (< 0.1% for RoHS).  We have several components that 
are very small (eg. 0.005" dia pins) that need to be inspected for gold 
thickness.  Do you have any for or against recommendations for the 
different types of equipment (hand held v/s bench top) and 
manufacturers out there?

Thank you,
