Scientific paper

The bulk of the pre-solar grains that have survived in primitive meteorites are submicron in size. Isotopic analysis of single grains requires highly sensitive mass spectrometric methods. An important role in future investigations will be played by the NanoSIMS, which is also characterized by high spatial resolution. Complementary methods are coming into operation (RIMS) or are being improved (noble gas mass spectrometry) up to the point where almost all atoms of a given trace element will be detected.
