The two techniques are used primarily in determining carbon 14 content of archaeological artifacts and geological samples.

These two radiocarbon dating methods use modern standards such as oxalic acid and other reference materials.

Once the organism dies, it stops replenishing its carbon supply, and the total carbon-14 content in the organism slowly disappears.

After pretreatment, samples for radiocarbon dating are prepared for use in an accelerator mass spectrometer by converting them into a solid graphite form.

The carbon atoms with triple positive charge further accelerate away from the positive terminal and pass through another set of focusing devices where mass analysis occurs.

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.

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 essentially two parts in the process of radiocarbon dating through accelerator mass spectrometry.
