Ams c14 dating

How does contamination affect AMS dating results?

The effect of contamination on bone samples that were subjected to AMS dating is dependent on these factors: type of contaminant, degree of contamination, and the relative age of the bones and the contaminant. If limestone has not been removed prior to AMS carbon dating, the radiocarbon age will be much older than the sample’s true age.

How does carbon dating work with AMS Carbon dating?

Modern sources of carbon can make the AMS carbon dating result of a bone younger than its true age. In general, infinite-age contaminants add considerable number of years to the true age of a bone sample, making it older than it is. Modern carbon, on the other hand, makes the bone sample significantly younger than its true age.

What are the disadvantages of AMS radiocarbon dating?

Disadvantages of AMS Radiocarbon Dating. An accelerator mass spectrometer, although a powerful tool, is also a costly one. Establishing and maintaining an accelerator mass spectrometer costs millions of dollars.

What is AMS dating and how does it work?

AMS dating involves accelerating the ions to extraordinarily high kinetic energies followed by mass analysis. Although more expensive than radiometric dating, AMS dating has higher precision and needs small sample sizes. Aside from archaeology and geology, AMS dating is also used in other fields like biomedical research and ocean sciences research.

How does contamination affect AMS radiocarbon dating results?

The effect of contamination on wood or charcoal samples subjected to AMS radiocarbon dating depends on the type of contaminant, degree of contamination, and the relative age of the samples and the contaminant.

How does carbon dating work with AMS Carbon dating?

Modern sources of carbon can make the AMS carbon dating result of a bone younger than its true age. In general, infinite-age contaminants add considerable number of years to the true age of a bone sample, making it older than it is. Modern carbon, on the other hand, makes the bone sample significantly younger than its true age.

Why do we use protein samples in AMS dating?

Laboratories use the protein component of bone samples in AMS dating because it is relatively acid insoluble and, therefore, can be easily isolated from the hydroxyapatite component and other carbonates.

How much sample should I send for AMS dating?

As such, to be on the safe side, we recommend that you send double or triple the amount we recommend for dry samples (e.g. instead of sending 50 mg dry wood, please send 100-150 mg of waterlogged wood for AMS dating ). Please consult the lab if you have insufficient amount of sample.
