Thermoluminescence is produced by radioactive decay particles (electrons), trapped in mineral grains.Heating the mineral (or exposure to light) releases electrons, and produces a flash of light, setting the clock to 0 (maybe only partial).Two sample preparation suites have been developed equipped for full mineral separation under safelight conditions.C dating, thermoluminescence is related to radioactive decay.It has forwarding offices in Australia, Brazil, China, Japan, South Korea, Taiwan, and the UK.Beta Analytic’s radiocarbon dating fees are inclusive of δ13C measurements by Isotope Ratio Mass Spectrometry (IRMS) and calendar calibration when applicable, δ18O for carbonates, and δD (deuterium) and δ18O for water.Systems have been supplied to a number of UK and European laboratories and are being used in support of labelling requirements.Additional facilities include low level beta counting, high resolution gamma spectrometry, and the use of NAA, ICPMS and a range of calibrated alpha, beta and gamma sources.

The lab is based in Miami, Florida, and is the world leader in Carbon-14 analyses since 1979.

We report here a new application of thermoluminescence (TL) for dating sand dunes.

This application assumes that exposure to sunlight causes bleaching of the geological TL of a sediment to a residual value and that TL accumulation starts again when the sediment is buried under fresh deposit and is thus shielded from the Sun.

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.
