Does radiocarbon dating work wiki
These two radiocarbon dating methods use modern standards such as oxalic acid and other reference materials.Although both radiocarbon dating methods produce high-quality results, they are fundamentally different in principle.Thanks to nuclear physics, mass spectrometers have been fine-tuned to separate a rare isotope from an abundant neighboring mass, and accelerator mass spectrometry was born.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.Detectors at different angles of deflection then count the particles.
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.Burning the samples to convert them into graphite, however, also introduces other elements into the sample like nitrogen 14.When the samples have finally been converted into few milligrams of graphite, they are pressed on to a metal disc.
