Compound specific radiocarbon dating
The Center for Applied Isotope Studies is and always has been a tracer-free facility: we do not accept, handle, graphitize or count samples containing Tracer or Labeled (Hot) C.In the following years, Libby and his team of researchers at the University of Chicago conducted a series of experiments testing this prediction and its implications.This may involve cleaning to remove obvious contaminants and/or reduction of particle size of the sample.
The goal of sample pretreatment is to isolate the carbon fraction required for radiocarbon dating and to remove carbon fractions that are altered or contaminated.Methods Used: All samples are physically examined to evaluate the composition and preservation of the sample, and to determine the appropriate pretreatment plan.In many cases further physical pretreatment is required.Selecting the appropriate pretreatment plan depends on the unique attributes of the sample itself, such as the sample type, potential contaminants, the burial context, and the size and preservation of the sample.Communication between the radiocarbon researcher and the sample collector is integral to this process.
The Center for Applied Isotope Studies offers consultation and full radiocarbon dating services for research and commercial clients. Noakes in 1968, the Center for Applied Isotope Studies is one of the largest and most comprehensive radiocarbon and isotope geochemistry facilities in the world.
