What elements can you trust?

  • Are you seeing some elements that are important to you? But you are not sure if they are real?
  • Understand how to handle elements with interfering spectra, for example: Ag and Sn; Co and Fe; Ba, V and Ti.

Spectra showing Ag and Sn peaks from a pXRF instrument with a Ag tube for a sample with 552 ppm Sn. Note peak overalps around 25 keV; modified after Sterk et al. (2018).
