Study of the uniformity of aerosol filters by scanning MA‐XRF [PDF]
X-Ray Spectrometry, 2017 Energy‐dispersive X‐ray fluorescence (XRF) is an attractive analytical method to determine the level of air pollution by heavy metals. The concentration of the filter in ng/cm 2 is obtained by direct comparison of the net characteristic line intensity of an element with that of a thin film ...

A new software for MA-XRF data visualization
XXIII Encontro Nacional de Modelagem Computacional e XI Encontro de Ciências e Tecnologia de Materiais (XXIII ENMC e XI ECTM),, 2020 Macro X-ray fluorescence (MA-XRF) analysis has experienced an exponential increase in usage during the last decade, especially in the field of conservation sciences. This was supported, in parts, by the unceasing development in robotics and electronics, being now possible to develop in-house systems at a much lower cost than commercially available ones.
