14c dating

Detectors at different angles of deflection then count the particles.At the end of an AMS run, data gathered is not only the number of carbon 14 atoms in the sample but also the quantity of carbon 12 and carbon 13.There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry (AMS).The two techniques are used primarily in determining carbon 14 content of archaeological artifacts and geological samples.

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.There are two accelerator systems commonly used for radiocarbon dating through accelerator mass spectrometry.One is the cyclotron, and the other is a tandem electrostatic accelerator.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.

Reference materials are also pressed on metal discs.
