NIST DTSA-II

NIST DTSA-II builds on the best available algorithms in the literature to simulate, quantify and plan energy dispersive x-ray analysis measurements.  The program implements analytical and Monte Carlo models for simulating x-ray spectra that can be compared directly to measured spectra.  The program implements the best available algorithms (including Filter-fitting and Pouchou and Pichoir’s XPP matrix correction algorithm) to provide the most accurate quantitative analysis available using energy dispersive detectors.  Finally, DTSA-II provides tools to help the analyst select the optimal standards and suitable instrument conditions to make accurate and precise measurements of composition.
