Accuracy in carbon 14 dating

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

The first part involves accelerating the ions to extraordinarily high kinetic energies, and the subsequent step involves mass analysis.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.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.

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