Carbon dating system
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.In mass analysis, a magnetic field is applied to these moving charged particles, which causes the particles to deflect from the path they are traveling.If the charged particles have the same velocity but different masses, as in the case of the carbon isotopes, the heavier particles are deflected least.
The first part involves accelerating the ions to extraordinarily high kinetic energies, and the subsequent step involves mass analysis.
There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry (AMS).
The two techniques are used primarily in determining carbon 14 content of archaeological artifacts and geological samples.
An accelerator mass spectrometer, although a powerful tool, is also a costly one.
Establishing and maintaining an accelerator mass spectrometer costs millions of dollars.
