研究者の方々から「放射性炭素年代測定に最も適しているのは、骨ですか？それとも歯ですか？」というご質問をよく頂戴いたします。
Beta Analyticでは、試験所としての付加価値を高める継続的な取り組みの一環として、δ15Nおよびδ13C測定に加えて、火葬されていない骨から抽出したコラーゲンのC:N（C/N比）、％C（炭素含有率）、％N（窒素含有率）の測定を行っております。
As part of the continuous efforts to enhance the laboratory’s value-added services, Beta Analytic now provides C:N, %C and %N measurements on collagen extracted from non-cremated bones in addition to δ15N and δ13C stable isotope analysis at no additional cost for samples sent for radiocarbon dating.
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.
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.
