Burning the samples to convert them into graphite, however, also introduces other elements into the sample like nitrogen 14.
When the samples have finally been converted into few milligrams of graphite, they are pressed on to a metal disc.
There are essentially two parts in the process of radiocarbon dating through accelerator mass spectrometry.
The first part involves accelerating the ions to extraordinarily high kinetic energies, and the subsequent step involves mass analysis.
An accelerator mass spectrometer has a run time of a few hours per sample.
Lastly, it must be noted that AMS measurements usually achieve higher precision and lower backgrounds than radiometric dating methods.
There are two accelerator systems commonly used for radiocarbon dating through accelerator mass spectrometry.
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.
At this stage, other negatively charged atoms are unstable and cannot reach the detector.
The negatively charged carbon atoms, however, move on to the stripper (a gas or a metal foil) where they lose the electrons and emerge as the triple, positively charged carbon atoms.
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.
There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry (AMS).
