Summary Elementar UK Ltd present present two pioneering new techniques for the analysis of larger and/or more polar organic molecules of biogeochemical interest which are traditionally considered unamenable for gas chromatography stable isotope ratio

Rationale: The hydrogen isotopic composition of lipids (δ 2Hlipid) is widely used in foodscience and as a proxy for past hydrological conditions. Determining the δ 2H values of large,well-preserved triacylglycerides and other uniquely microbial lip

Bog butters are large white or yellow waxy deposits regularly discovered within the peat bogs of Ireland and Scotland. They represent an extraordinary survival of prehistoric and later agricultural products, comprising the largest deposits of fat fou

Identification of a disinterred grave by molecular and stable isotope analysis

Autor: Ian D. Bull, Richard P. Evershed, Arpad A. Vass, Robert Berstan

Publikováno v: Science & Justice. 49:142-149

Confirmation of a potential disinterred grave was sought by GC and GC/MS analyses of lipid extracts of whole soils and white particulate matter. Fatty acid profiles and concentrations determined for three of the soils correlated with the deposition o

Publikováno v: Antiquity. 81:743-754

By extracting lipids from potsherds and determining the δ13C of the most abundant fatty acids, degraded fats from ruminant animals, such as cattle, and non-ruminant animals, such as pigs, can be distinguished. The authors use this phenomenon to inve
