the field deflects atoms of different masses differently (heavier atoms deflect less).

Targets tuned to different atomic weights count the number of c12, c13, and c 14 atoms in a sample.

However, when the organism dies, the amount of c14 declines such that the longer the time since death the lower the levels of c14 in organic tissue.Most samples require chemical pre-treatment to ensure their purity or to recover particular components of the material.The objective of pre-treatment is to ensure that the carbon being analyzed is native to the sample submitted for dating.For example, it was once standard practice to simply burn whole bones, but the results were eventually seen to be unreliable.Chemical methods for separating the organic (collagen) from the inorganic (apatite) components of bone created the opportunity to date both components and compare the results.
