Equipment

During the autumn of 2004, a new machine for Accelerator Mass Spectrometry was installed at the GeoBiosphere Science Centre. It is a compact machine (ca 6.5 x 4.5 m2) and based on some new technology – ‘Single Stage Accelerator Mass Spectrometry’ (SSAMS). It is used for 14C-dating and for quantification of 14C-labelled substances with applications within radioecology, ecology, medicine and biomedicine. To date (August 2016), about 8000 samples for radiocarbon dating have been analyzed on the new machine. At present the performance of the SSAMS system is as follows: precision (for samples younger than 5000 radiocarbon years): ± 35 14C-years, maximum datable age: ca 45000 BP, minimum sample weight: ca 0.2 mg of organic material (ca 0.1 mg of carbon). Supplier is National Electrostatic Corp. (NEC), Wisconsin, USA. The equipment was funded by the Knut and Alice Wallenberg Foundation and by the Swedish Research Council.
