An AMS instrument has been in operation at the NSF-Arizona Accelerator Facility for Radioisotope Analysis of the University of Arizona since 1982.
These include archaeology, oceanography, hydrology, geology, and paleoclimatology.
While AMS dating of archaeological and geological samples was once seen as the biggest application of the method, studies of global change (atmospheric-oceanic-climatological changes in the past), with potentially important applications to predicting future changes, now contribute the largest share of samples for analysis by this laboratory.
C) 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.
The financial and concomitant research benefits that will accrue from AMS by involving pharmaceutical companies and research institutes are evident.
The high throughput of samples and the accuracy of the results obtained by AMS will prove to be of increasing importance in agriculture and hydrology.
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 1000 times that amount.
In addition, the ability of AMS to measure the numbers of individual AMS radiocarbon dating is of value to multiple areas of Quaternary research.
