Fig. 6From: Analysis of trace metal distribution in plants with lab-based microscopic X-ray fluorescence imagingMap of the Compton peak at about 18.9 keV (a) corresponding to the Rh Kα line of Rh and Zn fluorescence map (b). Both images correspond to the two rosette leaves (position 0) of N. caerulescens. Point distance is 15 µm and integration time is 10 msBack to article page
