    For his contributions to the team that developed this process, Libby was awarded the Nobel Prize in Chemistry in 1960.A 1927 chemistry graduate of the University of California at Berkeley, from which he received his doctorate in 1933, he studied radioactive elements and developed sensitive Geiger counters to measure weak natural and artificial radioactivity.Mass spectrometers detect atoms of specific elements according to their atomic weights.They, however, do not have the sensitivity to distinguish atomic isobars (atoms of different elements that have the same atomic weight, such as in the case of carbon 14 and nitrogen 14—the most common isotope of nitrogen).The chemist who developed carbon dating, Willard Libby, won the Nobel Prize for his work.“Seldom has a single discovery in chemistry had such an impact on the thinking in so many fields of human endeavour,” one of Libby's colleagues wrote at the time, according to the Nobel Foundation.Only a minority of them carry a vintage date, however.

    Willard Frank Libby (December 17, 1908 – September 8, 1980) was an American physical chemist noted for his role in the 1949 development of radiocarbon dating, a process which revolutionized archaeology and palaeontology.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.Radiometric dating methods detect beta particles from the decay of carbon 14 atoms while accelerator mass spectrometers count the number of carbon 14 atoms present in the sample.Both carbon dating methods have advantages and disadvantages.
