The combination of the high energy available at the Munich tandem accelerator with the gas-filled analyzing magnet system (GAMS) allows to measure isotope ratios down to sensitivities of 10−16 (even 10−20 with respect to the bulk material). This unique sensitivity – especially in the mass region around A= 60 – allows a lot of applications like cross section measurements for astrophysically relevant reactions. Examples for measurements with a focus on astrophysics and geology will be presented.
