Production cross sections of residual nuclei obtained by knockout and fragmentation reactions of different tin isotopes accelerated at 1A GeV have been measured with the fragment separator (FRS) at GSI, Darmstadt. The new measurements are used to investigate the neutron-excess dependence of the neutron-and proton-knockout cross sections. These cross sections are compared to Glauber model calculations coupled to a nuclear deexcitation code in order to investigate the role of the remnant
