In situ spectroscopic methods such as infrared, Raman and UV/vis spectroscopy are powerful tools to gain insight into reaction mechanisms and catalyst actions in homogeneously catalysed reactions. These methods and combinations of them offer great potential for the real-time monitoring of reactions in the liquid phase, for mechanistic studies as well as process control and kinetics.
The question “What’s up doc?—High-precision isotopic analysis of essential metals in biofluids for medical diagnosis” is posed by Frank Vanhaecke and Marta Costas-Rodriguez. Research is under way as to the possibility of using high-precision isotopic analysis of metals in a biomedical context. The goal is to develop methods for medical diagnosis on the basis of isotopic analysis of mineral elements in biofluids, for diseases that can otherwise only be established at a later stage or via a more invasive method (e.g., a biopsy) and/or for prognosis purposes. Whilst this work is in a very early stage, it is known that various diseases have an influence on the uptake, metabolism and/or excretion of essential mineral elements and thus, can cause a difference in their isotopic composition in biofluids.
Karsten Hinrichs and Andreas Furchner describe “Infrared mapping spectroscopic ellipsometry”. Recent developments in fundamental and materials research have increased the value of mapping techniques such as ellipsometry. IR ellipsometry, since it operates in the mid-IR fingerprint region, provides complementary information on composition, structural properties and interactions
Tony Davies, Peter Lampen, Stephen Heller and Evan Bolton report on the future of the spectroscopic data collected as part of the EuroSpec programme. Its long-term preservation is being guaranteed through the PubChem Project of the US National Library of Medicine.
Kim Esbensen and Claas Wagner continue their study of “Heterogeneity—the root of all evil” in the Sampling Column. We would be most interested to hear readers’ views on our new column. Representative sampling is essential for most analyses to be relevant, and the column will move from its early theoretical introduction to practical solutions. Readers interested in learning more about the Theory of Sampling may be interested in the Proceedings of the 7th World Conference on Sampling and Blending which are now freely available at http://www.impublications.com/wcsb7.
In the Quality Matters Column, Peter Jenks reminds us about “BERM 14: it’s that time again!”. The latest in this line of conferences on Biological and Environmental Reference Materials is being held in the USA in October 2015.
This article, by Antonino Cosentino is “Multispectral imaging and the art expert”. Multispectral imaging systems are increasingly being used by scientists and conservators working with art. They can map and identify the consituents of the paint and any retouching that may have been carried out on works of art. They are also used to visually enhance old and faded documents.
“In vivo Raman spectroscopy of skin” is Paul Pudney’s topic. The skin is a most important part of our bodies. There is great interest in studying it to help understand the many skin diseases we are prone to, including cancer, to develop skin care products and, increasingly, as an alternative route to administer pharmaceuticals instead of through the gut. Raman spectroscopy is an exellent tool to study these, and has particular advantages in its ability to do so in vivo.
