At the moment we experience some delays caused by the Covid restrictions we have been subjected to. During 2021 we aim at reducing the overall turn around time to 3 - 4 months from arrival of the sample (present turn around time).

We offer express delivery (less than 1½ month) at an additional charge of 1500 DKK per sample. Express samples can only be submitted when agreed to. This is because of limited capacity for express samples. When submitting express samples please contact Marie Kanstrup for acknowledgement prior to sample submission.

For enquires please contact c14@phys.au.dk.

  • All 14C analysis includes δ13CAMS (±3‰). High precision δ13C can be requested (±0.05 – 0.1‰).
  • Expected 14C precision is 0.5 - 0.7%, corresponding to ±25 - 35 14C years on a sample that is 5000 14C years old. High precision measurements can be requested at an extra charge. Please contact c14@phys.au.dk.
  • Failed samples are charged 400 DKK + VAT.
  • Sample sizes are for normal sized samples (1 mgC). For further information on sample size, please see here.
  • On request and for an additional charge of 150 DKK + VAT we offer to send back surplus sample material to the submitter. Due to limited storage room we throw away samples one year after reporting the radiocarbon results
  • Cost for ready made targets (cathodes used on our system) or graphite (preferably with all necessary backgrounds) can be obtained by contacting c14@phys.au.dk
