Beta Analytic has provided high-quality radiocarbon dating services since 1979. The lab has demonstrated technical competence in the measurement of (a) natural levels of radiocarbon by AMS, and (b) stable isotope ratios of carbon, deuterium, nitrogen, and oxygen by Isotope Ratio Mass Spectrometry (IRMS).
As a tracer-free lab, we do not accept biomedical samples or any materials with artificial carbon-14, carbon-13, carbon-12 or any other isotopes to avoid the risk of cross-contamination.
As part of our quality control measures, internal standards are run daily in our in-house particle accelerators with SNICS ion sources. Multiple cross-checks are performed throughout each analysis. At least two (2) background measurements are done at the beginning and end of each run. To ensure accuracy in the results for the unknowns, 4 to 5 known-age QA standards are run in each AMS wheel.
We require results for the QA samples to fall within expectations of the known values before accepting and reporting the results for any sample.
How can Beta Analytic clients be sure their results comply with all the quality assurance requirements?

Our technical managers welcome discussion before, during, and after the analyses. We do not charge consultation fees.
Our account managers offer assistance and advice in Chinese, English, French, German, Italian, Japanese, Korean, Spanish and Portuguese.
If the sample size permits, Beta Analytic also provides stable isotope analysis for these materials at no additional cost:
We also offer stable isotope analyses NOT in conjunction with C14 dating.
