FAIR practice

Antony N. Davies

Following our articles on the FAIR initiative, we now look at some examples of the FAIRification of data handling, collection and archiving.

FAIR enough?

Robert M. Hanson, Damien Jeannerat, Mark Archibald, Ian Bruno, Stuart Chalk, Antony N. Davies, Robert J. Lancashire, Jeffrey Lang, Henry S. Rzepa

The Tony Davies Column offers a challenge to us all with another contribution on FAIR data, which should be Findable, Available, Interoperable and Readable. It is clearly the way we should all be going, everybody from manufacturers and software developers, through researchers to publishers needs to work together.

Determination of macroelements in potable waters with cell-based inductively-coupled plasma mass spectrometry

Valentina Lyubomirova, Veronika Mihaylova, Rumyana Djingova

With a wide range of concentrations of elements in potable waters, their accurate determination is difficult with ICP-MS. It is possible, using a cell-based instrument, to “tune” the signal sensitivity of particular elements and so keep all them within the dynamic range of the instrument.

COVID-19: Lock-down and up-skill

Antony N. Davies, Henk-Jan van Manen

With a significant proportion of our regular readership probably under home lock-down, we were wondering if we could help you at this difficult time by pointing out some useful online resources. So, when we finally come out of this pandemic, you could do so better skilled and more up-to-date than when we went in to it.

Planning for EuroAnalysis 2021

Antony N. Davies, Lutgarde Buydens

Tony and Lutgarde Buydens give us an update on the planning for the major EuroAnalysis 2021 conference, which is being held in Nijmegen, the Netherlands, at the end of August 2021. At this stage, they are keen to gather suggestions from readers on topics they would like to see covered. Groups are also invited to consider hosting their own event under the EuroAnalysis 2021 banner.

Direct analysis of trace elements in estuarine waters using triple-quadrupole inductively coupled plasma-mass spectrometry

Lionel Dutruch, Jörg Schäfer, Mélina Abdou, Daniel Kutscher

Estuaries are where much of our marine pollution is to be found, being the gateway between the land and the ocean. They are also where much of our seafood comes. So, knowledge of elemental contamination in estuaries is vital to protect us from the ingestion of polluted seafood.

What developments do you need to work more efficiently?

Antony N. Davies

Tony Davies continues his quest to find out what you all need to work more efficiently. You will remember that in the last issue, Tony introduced his survey to discover what developments were needed in spectroscopy by readers. Some of the initial responses are explored, and Tony finds that he has opened a “can of worms”.

If laser-induced breakdown spectroscopy was a brand: some market considerations

Vincenzo Palleschi
Vince Palleschi takes a slightly different approach to reviewing the current state of laser-induced breakdown spectroscopy (LIBS). He puts the strengths and weaknesses of LIBS in context and gives some examples of industrial applications.

The transparent witness: forensic examination of glass evidence at the Bundeskriminalamt

Peter Weis

This article is is a fascinating look into the use of laser ablation inductively coupled plasma mass spectrometry in forensic examination of glass fragments. These are often associated with crime scenes and easily “attach” to any people near them. Thus, they can be used to link criminals to their crime and to provide information on where a glass fragment might have originated.

Application of laser-induced breakdown spectroscopy for surface hardness measurements

Richard D. Pilkington, J. Stuart Astin, John S. Cowpe

Another surface problem is tackled by Richard Pilkington, Stuart Astin and John Cowpe: “Application of laser-induced breakdown spectroscopy for surface hardness measurements”. Measuring the hardness of materials is not entirely straightforward, and the authors show that laser-induced breakdown spectroscopy offers the potential for in situ hardness measurements, without prior sample preparation.

The use of inductively coupled plasma mass spectrometry to quantify chemical hazards in natural history collections: arsenic and mercury in taxidermy bird specimens

Stanislav Strekopytov

Stanislav Strekopytov tells us about “The use of inductively coupled plasma mass spectrometry to quantify chemical hazards in natural history collections: arsenic and mercury in taxidermy bird specimens”. It is quite shocking to learn about the use of poisons to preserve taxidermy specimens in the past. Nowadays it is essential that the dangers from such specimens are known before they can be handled by museum staff and particularly if they might be touched by visitors. ICP-MS analysis provides fully quantitative information on bulk contents of toxic elements in taxidermy specimens and so is well suited to this task.

What's up doc: High-precision isotopic analysis of essential metals in biofluids for medical diagnosis

Frank Vanhaecke, 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.

Two dimensional elemental mapping by laser-induced breakdown spectroscopy

Jan Novotný, Karel Novotný, David Prochazka, Aleš Hrdlička, Jozef Kaiser

The authors 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.

The impact of water pollution with chromium and nickel to the food chain

Sotiris Stasinos, Ioannis Zabetakis

Sotiris Stasinos and Ioannis Zabetakis have used ICP-MS to investigate the cross-contamination of food crops by heavy metals in ground or irrigation water. They show that this can occur easily in certain crops, which has serious health consequences for those consuming the food crop. As a consequence of their work, the European Food Safety Authority (EFSA) has been informed about the accumulation of Cr and Ni in food tubers and is taking action.

Determining spatial sodium distribution in fresh and aged bread using laser-induced breakdown spectroscopy

Maarten Scholtes-Timmerman, Cees Heddes, Martijn Noort, Sjaak van Veen

Bread is the major contributor to Na intake in the human diet. For this reason, it is expected that lowering the amount of salt in bread may lead to a substantial reduction in the sodium intake. However, lowering the amount of salt in bread has an impact on the flavour. Using LIBS, a fast and easy-to-use method could be set up to determine Na distribution in baked bread as an innovative tool to help the development of methods to reduce total sodium content in bread.

Characterisation of TiO2 pigments in commercial foundation creams: a synergic use of the ICP-AES, square wave voltammetry and sedimentation FFF techniques

Catia Contado, Antonella Pagnoni

TiO2 is widely used as a sunscreen UV filter and as a colouring agent in all types of cosmetic products. TiO2 has recently captured the attention of the scientific community since its safety assessment has been placed again under consideration. Inductively-coupled plasma atomic emission spectrometry (ICP-AES), square wave voltammetry (SWV) and sedimentation field-flow fractionation (SdFFF) are described in this article to characterise and quantify the TiO2 particles inside six commercial foundation creams.
