PY - Y1 - N2 - The development of accelerator mass spectrometry AMS during the last ten years has created a new revolution in the fields of radiocarbon 14C dating and other types of radioisotope analysis. The radiocarbon-dating method can be used to determine the ages of many types of carbonaceous material of up to about 50 ka in age.
It has been used almost exclusively to measure carbon The greatest advantage of radiocarbon dating by AMS is the ability routinely to measure samples containing 1 mg or less of elemental carbon, while previous methods have required nearly times that amount. AMS radiocarbon dating is of value to multiple areas of Quaternary research. While AMS dating of archaeological and geological samples was university of arizona radiocarbon dating lab seen as the biggest application of the method, studies of global change atmospheric-oceanic-climatological changes in the pastwith potentially important applications to predicting future changes, now contribute the largest share of samples for analysis by this laboratory.
