Description
Trace elements quantification is normally a difficult task in micro X-ray fluorescence analysis (microXRF), also inevitable in high flux synchrotron-based microXRF (SR-microXRF). However the high spatial resolution and high throughput of SR-microXRF are the advantages among chemical analysis techniques. In this work, we combined it with laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS), which provided quantitative output on trace elements, but in less spatial resolution. Both techniques show 2D chemical images in agreement. Therefore, we used quantitative information from LA-ICPMS to calibrate the SR-microXRF analysis, resulting in a quantitative 2D image with high spatial resolution.
