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.

Radiocarbon dating chemistry

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.

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.

Both carbon dating methods have advantages and disadvantages.

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.After pretreatment, samples for radiocarbon dating are prepared for use in an accelerator mass spectrometer by converting them into a solid graphite form.This is done by conversion to carbon dioxide with subsequent graphitization in the presence of a metal catalyst.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.An accelerator mass spectrometer, although a powerful tool, is also a costly one.
