At the moment we are working hard on reducing the delays caused by an excess of submitted samples in 2024. During the coming year we aim at reducing the overall turn around time to 3 - 4 months from arrival of the sample (present turn around time).

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

We offer express delivery (less than 1½ month) at an additional  50 % charge 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.

As of January 2026 we have adjusted the prices

We charge a handling fee of 300 DKK + VAT for each submission (series of samples submitted via online web submission)

• All ¹⁴C analysis includes δ¹³C_AMS (±3‰). High precision δ¹³C can be requested (±0.05 – 0.1‰) at a additional cost.
• 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 (1800 DKK + VAT). Please contact c14@phys.au.dk.
• Failed samples are charged 1375 DKK + VAT.
• Sample sizes are for normal sized C targets (1 mgC). For further information on sample size, please see here.
• On request upon submission and for an additional charge of 250 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
