The carbon isotope ratio can also be used to correct for isotopic fractionation in the radiocarbon measurement.The carbon dioxide is collected in a glass ampoule or converted to graphite for radiocarbon measurement on the AMS system.The best conventional counters can still achieve higher precision and lower backgrounds than an AMS system assuming a suitably large pure sample can be found.For this reason, the calibration curves for radiocarbon have usually been measured using counters. Many of these perform radiocarbon measurements and some of them will undertake sample pre-treatment.
In common with other kinds of mass spectrometry, AMS is performed by converting the atoms in the sample into a beam of fast moving ions (charged atoms).account, please select one or more formats and confirm that you agree to abide by our usage policies.If this is the first time you use this feature, you will be asked to authorise Cambridge Core to connect with your To send this article to your Kindle, first ensure [email protected] added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.
