Radiocarbon dating cost

Their are also many university labs around the world that do that.

20mg (i.e 2% of a gram) sample wrapped in aluminium foil and then zip lock is required.

Samples that require additional cleaning steps—for example materials with applied surface coatings, or where multiple fractions are dated—will cost more.

Discounts are given for academic and non-profit organizations.

The uncertainty changes according to the age of the sample and will be larger for older material.

Consultation with the Leibniz-Laboratory about the samples prior to submission is advised.

C dating service is for samples yielding at least 0.5 mg of carbon after chemical pretreatment (often acid-alkali-acid treatment of organic material).

The precision of radiocarbon dates for recent samples (younger than 2000 years) is better than 0.4% which equals /-35 years for the 1-σ statistical uncertainty of the measured age.

Normal handling will not contaminate most sample types, however, samples should be protected from sources of extraneous carbon.Radiocarbon dating is the principal method for determining the age of carbon-bearing materials from the present to about 50,000 years ago.The method takes advantage of the natural occurrence of a radioactive isotope of carbon (C in samples of ancient carbon compounds and comparing this with the amount in modern materials, it is possible to determine the time of cessation of carbon exchange with the atmosphere.* Sample and sample pretreatment should be documented, if possible a picture should show the quality of the prepared sample.** To establish the quality of the sample preparation outside our laboratory these samples should be accompanied by • at least two background samples • one or two standard samples (e.g. These samples have to be prepared in the same laboratory in substantially the same way as the unknown samples and will be charged as regular samples.
