In June 20-22 2017 the Itrax Advanced Operators training takes place in a beatiful Stockholm. The invitation for this training event is open for all users. These days give the user an overview of x-ray spectroscopy and of the advanced tools available in the Itrax Qspec software for x-ray spectra evaluation and determination of concentrations of all detected chemical elements, as well as the RediCore software for data compilation and display. This training puts the Itrax user in control of the analytical aspects, as well as phenomena like x-ray diffraction. Until now, dozens of Itrax users have enjoyed this yearly event and the deepened XRF knowledge it brings.
