From these data, concentration ratio of the isotopes can be known to allow evaluation of the level of fractionation.
The greatest advantage that AMS radiocarbon dating has over radiometric methods is small sample size.
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.
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.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.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.
