    A mass spectrometer is an instrument that uses a series of magnets to bend a beam of ions and then physically count how many there are, so with AMS radiocarbon dating, we can measure a carbon-12, 13 and 14 beam, and we measure the ratio of 14 to 13, and from that, we can tell how much C-14 is in the sample.So the most important things about AMS radiocarbon dating as opposed to conventional is that the sample size is much, much smaller.

    The method is relatively new because it needs very complicated instruments first developed for Nuclear Physics research in the late 20th century.For historical reasons, uncalibrated radiocarbon measurements are often referred to a half-life of 5568 years.However, this inconsistency is corrected during calibration [the reason for using the (Willard F.) Libby half-life of 5568 years instead of the correct one of 5730 years has to do with the finding in about 1962 that the true half-life was 573030 years.Dr Christine Prior is Team Leader of the Rafter Radiocarbon Laboratory at GNS Science.In this video, she compares conventional and accelerator mass spectrometry (AMS) radiocarbon dating.
