Confocal X‐ray fluorescence (XRF) spectrometry can be used to perform three‐dimensional elemental analysis, which is impossible using general micro XRF spectrometry without any collimating optics in the detection channel. In this study, we designed, for the first time, a new confocal line XRF (C‐L‐XRF) system that can obtain elemental information of a larger area and higher intensity in XRF analysis...
We developed a transportable micro‐XRF (µ‐XRF) spectrometer using a polycapillary X‐ray focusing half lens, which was placed between the sample and the detector. The total weight of the developed spectrometer was about 2 kg; its dimensions were 18(W) × 26(D) × 40(H) cm. The spatial resolution of the spectrometer with the half lens of a working (focal) distance of 30 mm was 171 µm at Fe Kα, which was...
