Portable XRF Instruments and Analysis

- a workshop focusing on the theoretical and applied applications of portable XRF instruments in geology, geochemistry, mineralogy and chemostratigraphy

Portable XRF instruments have become a main stream tool within the mining and exploration industry in wide ranging, diverse and novel applications. This workshop is designed to provide a theoretical background and framework with applied geological and geochemical examples for using "off the shelf" portable XRF instruments. The aim is to ensure that the user can judge data quality and understand the limitations various sample preparation with respect to data quality. Emphasis will be put on understanding and implementing data quality checks and method validation to achieve the best possible data accuracy for the task at hand

Topics to be covered include but not restricted to Which layer does the instrument see?, Mineralogical and Grain size effects? What is in the spectra? Qualitative Analysis 1x1, instrumentation, consumable components, limits of detection, beam times, instrument modes, appropriate QAQC, understanding the data, element false positives, user calibrations, matrix effects and sample preparation.

A variety of real-life case studies will be presented to demonstrate the challenges associated with application of portable XRF and where possible suggest appropriate solutions. The major emphases will be applicability of Portable XRF and appropriate protocols for generating and reporting of reliable "fit for purpose" results.

For a successful outcome the last hour of the workshop will be set aside for participants to present a short case study (5 min) on the challenges and application of portable XRF. We would encourage intending participants to submit 3 to 5 slides.
