I have been developing my own apps to work with XRF data - a selection of which is available here.
CloudCal is the centerpiece, it allows you to build empirical calibrations for a wide variety of XRF devices. It is also completely open source, you can visit its
GitHub page here. A simple
Tracer 5i Data tool allows you to parse the Results.csv file produced on the instrument to find the data relevant to your work. And Analyzer is a workhorse, it can take XRF data, Artax output, or a general spreadsheet and run PCA analysis and allow basic statistical analysis.
There are a few apps that are available to subscribe to via the
Paleoresearch Institute. This includes CloudCore, which is designed to analyze time series data produced by the tracer - it allows for radiocarbon date chronologies and complex elemental combinations. Also available is
Obsidian Source - this app connects XRF data (or any quantitative data) to a massive global obsidian database and associates artifacts with specific sources using a fingerprinting algorithm.
