ResumoMicroprobe analysis with PIXE (“micropixe”) combines advantages of other microprobes. It is a nondestructive method with detection limits at the ppm level. Delicate samples may be altered in cases, where high current densities are used. The content of the trace element Zr in mineral pairs can be used as a geothermometer. The first evidence of the trace elements Sr, Y, and Nb in lunar ilmenites, ulvöspinels, and armalcollites was obtained with the Heidelberg proton microprobe. Preparing a biological sample is a difficult problem. The influence of different preparation methods on elemental distributions in pollen tubes of lilium longiflorum is studied with the micropixe setup in Heidelberg. Knowledge of these influences may help to avoid artefacts during preparation of biological materials for any kind of microprobe analysis.
