X-ray fluorescence for cultural heritage: scanning biochemical fingerprints in archaeological shipwrecks

XRF-27_1-F1-small

Yvonne Fors, Håkan Grudd, Anders Rindby and Lennart Bornmalm tell us about “X-ray fluorescence for cultural heritage: scanning biochemical fingerprints in archaeological shipwrecks”. Two outstanding examples of the preservation of wood are the warships Vasa, in Stockholm and the Mary Rose in Portsmouth and this article looks at the role XRF has played in the preservation of the wood of both ships.

Application of Raman and photoluminescence spectroscopy for identification of uranium minerals in the environment

Perry-27_1-F1small

The “Application of Raman and photoluminescence spectroscopy for identification of uranium minerals in the environment” is described by Eric Faulques, Florian Massuyeau, Nataliya Kalashnyk and Dale Perry. Uranium forms a large number of compounds and complexes, and these are most helpful in the study of uranium, its chemistry and transport in the environment. Raman and photoluminescence spectroscopy provide complementary information and are powerful tools for direct speciation of uranium and identification of natural uranyl minerals relevant to the environment.

Two dimensional elemental mapping by laser-induced breakdown spectroscopy

Jan Novotný, Karel Novotný, David Prochazka, Aleš Hrdlička and Jozef Kaiser tell us about “Two dimensional elemental mapping by laser-induced breakdown spectroscopy”. LIBS seems to be finding increasing applications and to be receiving interest by the instrument manufacturers at present. The article provides an introduction to the technique and goes on to show how it can be used for elemental mapping in materials analysis.

Multisensor hyperspectral imaging as a versatile tool for image-based chemical structure determination

Hans Lohninger and Johannes Ofner describe “Multisensor hyperspectral imaging as a versatile tool for image-based chemical structure determination”. They describe the features of a software package that allows the combined analysis of hyperspectral data from different imaging techniques. This multisensor approach providing complementary information has many advantages.
