Carbon 14 dating and chemistry lab
With every shipment of many unknown-age samples we must add samples coming from oxalic acid transformation (which is the international standard reference material for all radiocarbon laboratories), inert samples to determine the background value (blanks) as well as known-age samples (secondary standards), coming from multi-laboratory calibration.This procedure assures a never-ending following of the quality, accuracy and precision of the results given to customers.Aside from radiocarbon dating, ISO/IEC 17005-accredited Beta Analytic also provides biobased/renewable carbon content testing to manufacturers, product distributors, and researchers worldwide for biobased products, biofuels, waste-derived fuels and their combustion emissions (CO2 gas).The lab also uses Carbon-14 analysis for natural product source testing on materials such as flavors, fragrances, essential oils, cosmetics and supplements to identify petrochemicals.Pharmaceutical companies evaluate drug metabolism by using a radiolabeled version of the drug under investigation. AMS biomedical laboratories use 14C as a tracer because it can easily substitute 12C atoms in the drug molecule, and it is relatively safe to handle. We are using the AMS method (Accelerator Mass Spectrometry). C-H-N analyses are also available now (possibility to get the percentages of C (Carbon), H (Hydrogen) and N (Nitrogen) for dry samples.The analyses are processed with a Leco CHN628 elemental analyzer.
Radiocarbon dating may only be used on organic materials.The other method is “Relative Dating” which gives an order of events without giving an exact age (1): typically artefact typology or the study of the sequence of the evolution of fossils.There are three carbon isotopes that occur as part of the Earth's natural processes; these are carbon-12, carbon-13 and carbon-14.AMS dating is possible on very small samples (a few milligrams).CEN has the equipment and expertise to prepare samples for AMS dating, which includes 2 major steps: C of your samples can also be done.
