The “OXI” XRF analysis method of Giles, Hurley and Webster  uses calibration standards to determine proportions of elements (present as oxides) in XRF fused bead (lithium borate glass) samples.
We recently re-established this method at Sheffield Hallam University using standard samples made using a Claisse LeNeo fused bead maker. This presentation describes how the standards were made and “OXI” was reinstalled on our PANalytical MagiX PRO XRF spectrometer. Giles, Hurley and Webster describe how this method was set up for 19 elements; we have extended this to include more elements and even more elements may be included in the future.
