The radiocarbon dating laboratory at the Center for Applied Isotope Studies was founded in 1968 and was originally called the Geochronology Laboratory of the University of Georgia.
CAIS is the oldest ISO/IEC 17005 accredited radiocarbon laboratory in the world.
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).
The mass of these ions is then measured by the application of magnetic and electric fields.
Definition: AMS (Accelerator Mass Spectrometry) radiocarbon dating is a way to obtain radiocarbon dates from samples that are far tinier than that needed for standard radiocarbon dating.
Standard c14 dates require amounts of between 1 and 10 grams of charcoal; AMS can use as little as 1-2 milligrams, and under special circumstances to samples as small as 50-100 micrograms.
We customize reports for each project, providing the information you need, in the format you prefer.This is a large nuclear particle accelerator based on the principle of a Tandem van de Graaff Accelerator operating at 0.2 to many million volts with two stages operating in tandem to accelerate the particles.At the connecting point between the two stages, the ions change charge from negative to positive by passing through a thin layer of matter ("stripping", either gas or a thin carbon foil).Molecules will break apart in this stripping stage.C measurements) is one reason for the exceptional abundance sensitivity of AMS.-counting method) or by directly counting the radiocarbon atoms using a method called Accelerator Mass Spectrometry (AMS).
