Here is a link to an article that I read recently in US Tech about an XRF
system made by Fischer Technology - sounds rather interesting in its
capability to distinguish layers and composition - do any of you have
experience with this system, or any feedback about it?

Hi, on a related note...we are looking for a XRF too... can you share the
manufacturer's details and pricing on the XRF you have??

Hi Netters,

we've just become the happy owners of a tabletop XRF analyzer. Works fine,
shows what we need, we have already rejected non-compliant parts, etc.

But there is a litle something... The soft allows for creating applications,
so we can declare that the component has layers, i.e. you can define Au over
Ni over Cu. At this moment the measurements will tell you what is the
thickness of each layer and what is the composition of each layer. Normally
this increases the accuracy of the measurements.

If I x-ray considering layers, I get readings for a SnPb layer that show 14%
lead. If I don't use the layered routine and I shoot through the bulk of the
surface, the Pb goes away, the influence of the Ni and mainly of the Cu
dilutes the Pb to below RoHS threshold.

Hence the question, how should I measure? What is the homogeneous material,
each layer or the bulk?

Thanks,
Ioan
