Researchers often ask which material is best for radiocarbon dating – bones or teeth. Based on our lab’s experience, either material can provide the best date. However, the environmental conditions for these materials should be taken into account during sample selection.
There are two possible reservoir corrections applied to a radiocarbon date for marine carbonates – the localized reservoir correction (DeltaR / DeltaRErr) and the global marine reservoir correction. The former is provided by the client to the lab before the analyses while the latter is part of the calibration program.
It is possible to date fired clay bricks, but it depends on how the bricks were manufactured and what types of contamination may have been absorbed into the bricks since they were put in place.
Just like sediment, it is better to date the macrofossils found in sand. In the absence of macrofossils, sand can be dated if there is an organic material on the surface of the sand. If there is enough carbon present in the organic coating, a radiocarbon date can be obtained.
What if there are several materials found in sediment (e.g. wood, charcoal, seeds) but each one does not meet the lab’s minimum sample size requirement, can a mixture of materials be dated?
We have dated beeswax, sometimes with good success, sometimes not. This is because no pretreatment for organic contaminants can be applied. Thus, if any younger or older carbon has been incorporated in the beeswax, it will be represented in the result.
ISO/IEC 17025:2017-accredited radiocarbon dating laboratory Beta Analytic has recently opened a sample forwarding office in Taipei City, Taiwan. The company can now bill in Taiwan Dollar (TWD) via its new office. Clients who will pay in US Dollars (USD) will be billed via the Miami headquarters.
In addition to conventional collagen extraction, ISO/IEC 17025:2017-accredited Beta Analytic now offers ultrafiltration of bone collagen in response to clients’ need for additional pretreatments specific to their research opinions and objectives.
Beta Analytic Inc., the world’s largest professional radiocarbon dating laboratory, has successfully completed its ISO/IEC 17025:2017 re-accreditation assessment, according to Perry Johnson Laboratory Accreditation, Inc. (PJLA). Beta Analytic maintains its ISO/IEC 17025:2017 accreditation as part of its commitment to provide high-quality results and excellent customer service to clients worldwide.
To better serve clients in South Korea, ISO/IEC 17025:2017-accredited Beta Analytic has opened a sample forwarding office in Seoul. The initiative is part of the company’s commitment to provide archaelogists, geoscientists, forensic experts, and other researchers in Asia with high-quality radiocarbon dating services. All samples submitted to the forwarding facilities are sent to the Miami […]
