Mickiewicz University in Poznan The Laboratory is kept by the Foundation of the A.Mickiewicz University and is housed in the area of the Poznan Park of Science and Technology C laboratories are usually open to cooperate with wide community.Although the levels of contamination are acceptable in a biomedical AMS facility, it is not acceptable in a radiocarbon dating facility. Biomedical AMS facilities routinely measure tracer-level, labeled (Hot) 14C samples that are hundreds to tens of thousands of times above the natural 14C levels found in archaeological, geological, and hydrological samples. These two operations should be absolutely separate. The amount of carbon dioxide in the atmosphere today is higher than that at any time in the last 420,000 years (figure 1).While the roughly 30% increase in CO also occurred in the past, presumably related to shifts in global climate.
Pharmaceutical companies evaluate drug metabolism by using a radiolabeled version of the drug under investigation.
On longer timescales, the radioactive decay of C provides information on slower exchanges with the much larger stores of carbon in the deep ocean and the carbon stabilized in soils and sediments.
Radiocarbon is the best and often the only way to quantify rates of exchange of carbon among reservoirs.
By measuring this ratio, we can calculate the age of a sample. But radiocarbon comprises only about one trillionth of the carbon in living organisms. Painstaking work is required to isolate and measure only the original sample carbon and produce a reliable radiocarbon date, one that is scientifically accurate and numerically precise. At Aeon Laboratories, we pursue this goal with innovative proprietary technology, the skill and discipline required to execute exacting procedures, and a thorough understanding of chemical and biological principles.
As part of its commitment to provide high-quality results to its clients, ISO/IEC 17005-accredited Beta Analytic does not accept pharmaceutical samples with “tracer Carbon-14” or any other material containing artificial Carbon-14 (14C) to eliminate the risk of cross-contamination.
