The lab also offers C: N, %C and %N measurements on collagen extracted from non-cremated bones in addition to δ15N and δ13C at no additional cost for samples sent for radiocarbon dating.The lab also provides stable isotope analyses on a standalone basis.

The lab accepts biobased products, biofuels, waste-derived fuels and their combustion emissions (CO2 gas).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.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.Read More 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 at no additional cost for samples sent for radiocarbon dating.

-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.

Your computer or phone screen, the chair you are sitting on, you, and I are all made out of atoms.

If we were to zoom in further using our very technologically advanced and imaginary chemistry goggles, we'd be able to see that the atom itself is made out of subatomic particles with specific properties. The nucleus is made up of protons and neutrons, and electrons are localized outside the nucleus.

Since electrons have a negative charge, they are attracted to the positively charged protons in the nucleus.

This gives an atom its stability, and we can think about this mathematically using Coulomb's law.

On a very simplistic level, we can represent an atom using Figure 1: electrons to balance out the positive charge from the protons. This particular atom of helium happens to have two neutrons.
