Biochemical markers in archaeological shipwrecks; determination of Sulphur and Iron in wood with Itrax Multiscanner
A group of Swedish researchers have presented an article in Nature, where they map the accumulation of inorganic elements in archaeological wood from the Swedish warship Vasa and from the English Mary Rose. Sulphur has accumulated in the wood through biogeochemical processes and together with Iron, it constitutes a threat to the drying wood when combined with oxygen. Sulphuric acid is formed in big quantities and constitute a long term threat to these important parts of the cultural heritage. The XRF analyses for Sulphur, Iron and other chemical elements in the ships wood were performed with Itrax Multiscanner.
