XRF and XRD best practice...

2014-02-14 Thread Mibeck, Blaise
Hello all, I use Rietveld primarily for quantitative phase analysis of rock samples. We collect XRF and XRD data on our samples. Is there a best practice for using these data together? Or a recognized method or procedure for evaluating the agreement between the two? Can the XRF be used to res

There are many ways how elemental analysis (e.g. by XRF) can be used to guide the XRD phase quantification. This becomes especially relevant when using "2 in 1" equipment like "Thermo ARL 9000 Workstation". The XRD-XRF combination is often used (by various ways) in cement industry - you may sear

Hi. I think XRF can help only in case of simple samples or, e.g., to disclude some "strange" elements, by proving there's none of them in the particular sample. But when you have, lets say, a mixture containing a spinel and periclase (MgO), then you won't be able to confirm by XRF itself that all t
