Carbon dating of wood
Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for carbon-14 measurements.
The lab is based in Miami, Florida, and is the world leader in carbon-14 analyses since 1979.
This means that although they are very similar chemically, they have different masses.
The total mass of the isotope is indicated by the numerical superscript.
Thermoluminescence dating: this method is associated with the effect of the high energy radiation emitted as a result of the decay or radioactive impurities.
Radiocarbon dating is the principal method for determining the age of carbon-bearing materials from the present to about 50,000 years ago.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.We also offer liquid scintillation analysis using an extra low background Quantulus 1220 for high precision measurements on benzene.Very small samples (less than 300 mg) are analyzed by accelerator mass spectrometry (AMS).
