The Groningen AMS target laboratory has a capacity of producing 2000 targets annually. Samples are combusted by a CN analyser/mass spectrometer combination. A 25-fold graphitization setup is employed. We emphasize a combination of automation and quality. Backgrounds of better than 45 ka are routinely achieved. Test measurements on contamination, backgrounds and fractionation are reported.
