X‐ray fluorescence analysis of heavy elements using MIRRORCLE‐6X

X‐ray fluorescence analysis of heavy elements was performed using the portable synchrotron ‘MIRRORCLE‐6X’ for peak injection currents 10–50 mA and four different target conditions. It is observed that the spectrum for current 30 mA and ‘no target’ shows narrow peaks of fluorescent X‐ray and high resolution of the peak position without a pile‐up effect.
