pXRF correctionCorrection and QA/QC - as simple as uploading the raw data.

pXRF machines drift. Is your data corrected?

How it works


Upload your certified standard values


Upload files from the pXRF machine, including sample IDs


Download corrected data and QA/QC reporting


  • Standards analysed together with the samples are used to calculate the correction factors
  • The algorithms used are given in these papers:
  • Fisher, L., Gazley, M.F., Baensch, A., Barnes, S.J., Cleverley, J. & Duclaux, G., 2014. Resolution of geochemical and lithostratigraphic complexity: a workflow for application of portable X-ray fluorescence to mineral exploration. Geochemistry: Exploration, Environment, Analysis, 14(2), pp.149- 159. PDF

  • Use linear or reduced-major-axis regression
  • Complete control over the standards and calculation configuration used for each element
  • Configure the correction acceptance criteria, e.g. 0.9 > m > 1.1 and R2 > 0.8.
  • Organize data from different machines or locations into Projects
