This website is designed to serve two functions. The first is to provide guides to using handheld/portable X-Ray Fluorescence (XRF) in the non-destructive analysis of objects in situ. The second objective is to give you an idea of the capabilities of this type of analysis.You can learn to use the software using step-by-step tutorials or video Manuals for the use of the Tracer can be accessed. Written descriptions of concepts in XRF analysis are organized by topic. You can access Bruce Kaiser’s workshop folder to explore the different applications available as well.If you have any questions, you can use the contact link to get in touch. I also recommend joining the pXRF for Cultural Heritage group to stay in touch with how people all over the world use XRF non-destructively and in-situ.
