An accelerator mass spectrometer, although a powerful tool, is also a costly one.Establishing and maintaining an accelerator mass spectrometer costs millions of dollars.Thanks to nuclear physics, mass spectrometers have been fine-tuned to separate a rare isotope from an abundant neighboring mass, and accelerator mass spectrometry was born.A method has finally been developed to detect carbon 14 in a given sample and ignore the more abundant isotopes that swamp the carbon 14 signal.Reference materials are also pressed on metal discs.These metal discs are then mounted on a target wheel so they can be analyzed in sequence.Radiometric dating methods detect beta particles from the decay of carbon 14 atoms while accelerator mass spectrometers count the number of carbon 14 atoms present in the sample.

The first part involves accelerating the ions to extraordinarily high kinetic energies, and the subsequent step involves mass analysis.

These two radiocarbon dating methods use modern standards such as oxalic acid and other reference materials.

Although both radiocarbon dating methods produce high-quality results, they are fundamentally different in principle.

Detectors at different angles of deflection then count the particles.

At the end of an AMS run, data gathered is not only the number of carbon 14 atoms in the sample but also the quantity of carbon 12 and carbon 13.

Burning the samples to convert them into graphite, however, also introduces other elements into the sample like nitrogen 14.
