When an X-ray tube is used as the excitation source in XRF analysis it is critical to know the number and the energy distribution of the photons striking the sample. This can become especially complicated when primary filters are used to modify the excitation source. In addition, knowledge about the detector crystal thickness and correction functions are also essential for elemental analyses. In order to facilitate the analysis process we have developed the THTUBE.exe program that in effect inverts the formula for determining the elemental concentrations to find the best estimate of the excitation function, detector crystal thickness and correction functions using known concentration values, sample and setup information.
