Elemental micro patterns in tree rings - a feasibility study using scanning proton microprobe analysis

The feasibility of applying particle-induced X-ray emission spectroscopy (PIXE), using a scanning proton microprobe (SPM), to trace-element analysis in wood and bark samples is demonstrated. Detection limits of the order of 1-10 ppm are reached for several elements. Elemental X-ray images of the ana...
