Rheo-nuclear magnetic resonance spectroscopy: a versatile toolbox to investigate rheological phenomena in complex fluids

“Rheo-nuclear magnetic resonance spectroscopy: a versatile toolbox to investigate rheological phenomena in complex fluids” is Claudia Schmidt’s topic. Rheology is an important science, and NMR has a number of uses within it. However, challenges remain for the simultaneous measurement of rheological and NMR parameters.

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.

Theory of sampling (TOS)—the missing link before analysis

Thi is a new column on Sampling, edited by Kim Esbensen and Claas Wagner. I really only became aware of the Theory of Sampling (TOS) following conversations with Kim at the NIR-2013 conference in La Grande Motte, near Montpellier, France. I won’t steal Kim and Claas’ thunder by going into detail, but I see this new column as a perfect complement to our others. Ian Michael, editor.

The last furlong (6). The finishing line is in sight!

This is Tony’s last column for Spectroscopy Europe. It is explores an idea that he has been developing for over 30 years, although as Tony points out the story starts around 3500 years ago.

Commutability or reference materials: practical implications for users

Peter Jenks seeks to show where it is important to check the CRM or RM you are using includes a clear statement of commutability, and when and where it can be largely ignored.

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.

Elucidating structural and compositional changes in plant tissues and single cells by Raman spectroscopic imaging

“Elucidating structural and compositional changes in plant tissues and single cells by Raman spectroscopic imaging” is the topic of the next article by Batirtze Prats Mateu, Barbara Stefke, Marie-Theres Hauser and Notburga Gierlinger. Understanding plant cells is important for the best use of plants in traditional and new applications. Raman spectroscopic imaging represents one of the best ways to unravel the molecular structure in the native environment of plant tissues.

A head in the clouds?—Part two: exploring distributed, multi-server 1H NMR prediction

The Tony Davies column is a joint effort by Tony (A.N.) Davies, Mohan Cashyap, Bob Lancashire and Bob Hanson on “Exploring distributed, multi-server 1H NMR prediction”. This is the second part of the column’s investigation into the use of cloud-based services in the analytical arena. It describes a web page linking services from multiple sites on both sides of the Atlantic to deliver molecular structure drawing, 3D structure representation, name to structure conversion and display of data generated by linking chemical structures to 1H NMR prediction. May I reiterate Tony and Mohan’s plea for information on such cloud-based solutions, whether commercial or not. These can be sent to me ( This e-mail address is being protected from spambots.

Into the future: changes to ISO 17025 and ISO Guide 34

In the Quality Matters column, Peter Jenks and John Hammond look “Into the future: changes to ISO 17025 and ISO Guide 34”. There is a lot happening at present around ISO/IEC 17025 and ISO Guide 34, which together provide the framework for the development and use of certified reference materials in analytical laboratories around the world. John reports from the recent 37th meeting of the Reference Material Committee of ISO (ISO/REMCO) and provides an update on the topic of “commutability”.
