WebAnalysis of δ 34 S for dietary work is currently being developed and should be available by autumn 2012. To date, of the published isotopic archaeology studies conducted on Scottish material, it is notable that few of these studies were undertaken by Scottish research teams or in Scottish laboratories. WebHow does isotopic analysis work? By measuring the ratios of different isotopes in bones or teeth and using scientific knowledge about how they occur in nature to trace them back to the sources that they came from, archaeologists can find out many things about an individual, such as what their diet was like and the environment they grew up in.
Isotope-ratio mass spectrometry (IRMS) is a specialization of mass spectrometry, in which mass spectrometric methods are used to measure the relative abundance of isotopes in a given sample. This technique has two different applications in the earth and environmental sciences. The analysis of 'stable isotopes' is normally concerned with measuri… WebThe analysis of nitrogen isotopes (𝛿 15 N) are often used in combination with carbon isotopes as they provide further information on the trophic level of the organism in question since an enrichment (2-6‰) in 𝛿 15 N occurs at each progressively higher trophic level (Sealy, 2001). Furthermore, 𝛿 15 N can be used to interpret when food sources are of terrestrial …
