Abstract
An energy-dispersive system is described for element mapping by X-ray fluorescence spectrometry. Unlike Gruker’s tomographic system, a point-shaped beam from an X-ray tube is used for direct mapping. Typical spatial resolution of the system is about 260 μm. Element maps obtained for damaged leaves and animal livers demonstrate possible applications to biological problems.

We also obtained calcium and potassium maps of this sample and found that the calcium concentration is increased and the potassium concentration is decreased in the damaged part. However, since this is a rather common phenomenon for the damaged cabbage leaf, it is apparently the result of tissue destruction (see, T. Yoshikawa, Bunseki, 1984, 313).
