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.

Acids may be used to eliminate contaminating carbonates.Libby calculated the half-life of c14 as 5568 ± 30 years.This means that half of the c14 has decayed by the time an organism has been dead for 5568 years, and half of the remainder has decayed by 11,136 years after death, etc.Many laboratories now use liquid scintillation counters with the samples being converted to benzene.All of these counter types measure the C-14 content by monitering the rate of decay per unit time.
