Limitations of radiocarbon dating
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.
The two techniques are used primarily in determining carbon 14 content of archaeological artifacts and geological samples.
Due to the sensitivity of accelerator mass spectrometers, carbon dating small particles like blood particles, a grain, or a seed have been made possible.
Accelerator mass spectrometry also takes less time to analyze samples for carbon 14 content compared to radiometric dating methods that can take one or two days.
Ions from a cesium gun are then fired at the target wheel, producing negatively ionized carbon atoms.
These negatively ionized carbon atoms pass through focusing devices and an injection magnet before reaching the tandem accelerator where they are accelerated to the positive terminal by a voltage difference of two million volts.
