We here report on two technical research projects of the Quaternary Isotope Laboratory (QL) vis , (1) the use of thermal diffusion isotopic enrichment to extend the technical range of 14 C dating, (2) the preparation of samples for ion counting using a Van de Graaff tandem accelerator. The second project is carried out in cooperation with, and partly at, the Nuclear Physics Laboratory. A gain in dating range of 3 to 4 half-lives can routinely be obtained with the QL and the Groningen enrichment systems. The same gain in age range can be obtained for ion counting with a simplified system that requires only 0.5 to 2g of carbon and 3 to 7 days enrichment time. A method to convert CO 2 quantitatively via CO into carbon is described. For short intervals the carbon deposit yields good 12 C— beams. We also give a different procedure to make graphite-like carbon samples. The preparation of beryllium metal samples is given last
