The Oxalic acid standard was made from a crop of 1955 sugar beet. The isotopic ratio of HOx I is -19.3 per mille with respect to (wrt) the PBD standard belemnite (Mann, 1983). T designation SRM 4990 C) was made from a crop of 1977 French beet molasses.

Since protons and neutrons weigh about the same, the atomic mass of ordinary carbon is 6 6 = 12.The rest of the carbon isotopes are only of laboratory interest. Poznan Radiocarbon Laboratory is the first such institution in the Central-Eastern Europe.Performance of the Poznan Radiocarbon Laboratory (PRL) is possible due to a close collaboration with the AMS Laboratory (LAMS), housed at the same floor, and leaded by the same person.Therefore, communication between PRL and LAMS is fast and effective.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.Laboratory address: Poznan Radiocarbon Laboratory ul. Our goal for these products is a high degree of automation and versatility, as well as a compact and user-friendly design achieved through excellent engineering.To understand this process we must first understand a little bit about the atoms themselves and how they get their the atmosphere at the time of cessation of respiration or metabolism, such as the harvesting of a crop or grass living its natural life in a field.Special considerations are needed to apply the testing method to materials originating from within artificial environments.
