Abstract Dust capture cells on board the LDEF (Long Duration Exposure Facility) satellite were designed to enable the study of the elemental and isotopic composition as well as the size distribution and flux of interplanetary dust particles (IDPs), destructively collected at 500 km altitude over a period of several years. This is a report on simulation experiments of high velocity impacts on the capture cells which have been performed in order to investigate the relationship of the particle's chemical composition before the impact to the composition of the residue on the cell. To that end, both the projectile material and the impact residues have been analyzed with secondary ion mass spectrometry (SIMS). It is found that elemental fractionation occurs during the impact and that the magnitude of fractionation is related to the volatility of the elements.
