"Radiocarbon" the journal of record of the field, has been published by the Arizona Board of Regents since 1989.

Accelerator Mass Spectrometry (AMS) is a technique for measuring the concentrations of rare isotopes that cannot be detected with conventional mass spectrometers.

After chemical pre-treatment, the samples are burnt to produce carbon dioxide and nitrogen.

Accelerating the ions to high energy has one more advantage.

AMS, on the other hand, can in principle detect a much higher proportion (typically about 1% of the total) allowing sample sizes to be smaller by a factor of about a thousand.

The method is relatively new because it needs very complicated instruments first developed for Nuclear Physics research in the late 20th century.

The chemical pre-treatment depends on the type of sample.

As an example bones are treated as follows: Several of these procedures are done in an automated continuous flow system.

The sample is put into the ion source either as graphite or as carbon dioxide.
