The Center for Applied Isotope Studies offers consultation and analytical services relating to light stable isotopes (δ13C, δ15N, δ18O, δ34S), as well as strontium (87Sr/86Sr) and lead-series isotopes, for archaeological and paleontological applications.

Our full-service Pretreatment Facility allows us to offer many specialty services, including collagen extraction, bone and enamel bioapatite pretreatment, and micro-milling.

With over 20 mass spectrometers dedicated to the analysis of light stable isotopes, strontium, and lead, we are proud to offer high-precision measurements and fast results – typically in three weeks or less.






Sample Submission Guidelines

Sample submission guidelines:

If you are a first-time client, please contact us before sending your samples

  1. Package samples in clean, well-labeled, tightly sealed, crush-proof containers. Use the sample size table to determine the optimum sample size based on the material type.
  2. Complete the radiocarbon dating sample submission form. If you are sending more than one sample, you can put them all on the same form. Make sure you assign each sample a unique identifier. Include a printed copy of the form in the package.
  3. Note: If you are sending 10 or more samples, please also send us an electronic sample inventory (excel file)—you also qualify for a 10% volume discount.
  4. Address the package to:

Radiocarbon Dating Lab
Center for Applied Isotope Studies
120 Riverbend Road
Athens, GA 30602 USA



Will I get the rest of my samples back?

Our policy is to archive excess sample materials. If you would like us to return the unused portion of your samples, please let us know and we will prepare the materials for shipping at your expense.


Do you provide services for private individuals?

No, we only provide consulting services for academic institutions and commercial operations.


How much sample should I send? What is the smallest sample you can measure?

It depends on the type of material you are working with. “Minimum” and “optimum” sample sizes are included in the fees chart. If your sample is smaller than the minimum, or is a material not listed, please contact us.


How much does radiocarbon dating cost? What is included in this fee?

Most samples are $450; bones are $500. We report conventional radiocarbon age (14C yr BP), percent Modern Carbon (pMC), δ13C, as well as calibrated calendar dates (by request). For certain material types, we also report δ15N or δ18O. See fees chart for details.


Can I get a discount?

We offer 10% volume discount for batches of 10 or more samples. We also offer discounts for researchers affiliated with the University System of Georgia and Emory University. Contact us for details.


When will I get results?

The turnaround time for most standard analyses is 2–3 weeks. Large batches or samples requiring additional analysis may take longer. Please contact us for details.


How should I package my samples?

There are many acceptable methods, but the most important things to consider are that they are clearly labeled and easy to open and close. We prefer tightly-sealed glass or plastic vials for small or delicate samples. Plastic bags and aluminum foil are usually fine for larger samples. We prefer see-through containers when possible.
