Those capabilities are common to most fluoroscopes actually. The XRF's have a function for providing a spectrum, or spectrum analysis of the specimen tested. Most XRF equipment can provide a visual representation of the level or amount of the element detected, you've probably seen similar screen images on shows like CSI where a sample is placed in a chamber and the screen shows spiked charts, while in CSI they are probably using an SEM or AA it is the same visual depiction.

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? http://www.us-tech.com/np/ustech/files/guestD1573535530A.html Sara Rice Foresite Inc. 1982 S.

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?? Amol Kane M.S (Industrial Eng.)

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?
