The New Zealand physicist Ernest Rutherford, suggested in 1905 that the exact age of a rock could be measured by means of radioactivity.For the first time he was able to exactly measure the age of a uranium mineral.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.
have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.We encourage our submitters to contact us to discuss their samples and research objectives. We pride ourselves on personal and rapid email contact with submitters to determine radiocarbon dating requirements and ensure delivery of reliable and accurate radiocarbon results.

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.
The SEM also has commercial applications including the imaging and analysis of contaminants, particularly important in the food, dairy and water industries where quality assurance is important.
