Peter McIntyre and Tony Davies remember Bill George, a real Welsh character and educator whose style and charisma influenced many to go on and not only stay in science but to rise to leading positions either in industry or academia.

In quantitative analysis, is it better to weigh materials when making up standard solutions or to use volumetric techniques? Traditionally, the answer has been “volume”, however, things may not be as straightforward as they seem. Henk-Jan and colleagues have conducted a new experiment, using robots for both sample preparation and spectroscopic analysis which may provide a definitive answer. Unfortunately, the answer must wait for publication of their paper, but Tony and Henk-Jan’s history of this question makes interesting reading nevertheless.
Whilst automation is not a panacea, it can improve the accuracy of manual tasks as well as freeing up our time for more challenging tasks. The authors explore some particular examples they have come across and lessons learned from them.
Tony Davies and Mohan Cashyap discuss this topic with help from a number of industry experts. Whilst there are undoubted computing and networking issues for regulated industries in allowing working from home as if the user was in the lab, they are not insurmountable.
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.
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.
The authors offer many useful points to consider when using pre-processing techniques.
A recent conference on Extractables and Leachables in Hamburg not only allowed two ex-colleagues to meet after many years, but also provided information on developments and trends in the regulatory environment. Not only are ever lower levels of detection required, but also analytical requirements are being placed on companies further back in the materials’ supply chain that have not had to make such considerations before.
Do you have the budget for a new instrument? Well, stop… wait! Tony Davies and Marian Draaisma have very useful guidelines. They run through questions you should be asking yourself (and your team), information you should gather and how you should go about the selection process for a new spectrometer. If you’re not buying just now, this is definitely a column you will want to bookmark for future reference.
Tony Davies and Roy Goodacre raise some issues around the reliance just on vast quantities of data collection in omics experiments. As they put it, should we “just keep throwing the mass spectra, nuclear magnetic resonance data sets and our ion mobility fingerprints onto a big pile for the statisticians to fight over?”.
Tony Davies, Peter Lampen and Robert Lancashire are worried about their metadata, or perhaps the lack of it. With the explosion of data and ways to mine and make use of it, having accurate and appropriate metadata about analytical data sets is vital if they are to be reused efficiently or at all. This is also an area that is being increasingly targeted by regulators, with the US FDA issuing guidance at the end of 2018; others will follow. You have been warned.
Hafiz Abdul Azeem recently presented some interesting results from his work on atmospheric aerosols. Following their capture, he combined the optimisation of the extraction process with chromatographic separation and mass spectroscopic detection to identify various sources of pollution through their emission marker fingerprints.1 One spin-off of this work has been the use of a specific biomarker from cellulose combustion to potentially warn of low-heat smouldering in, for example, agricultural materials in bulk storage.
The authors tell us about an initiative to promote analytical spectroscopy to a range of people from school children and their parents to Dutch chemists. PAT is the key.
Tony raises the question of whether those implementing change consider sufficiently the effects on those who need to implement it or who will be affected by it. I am sure that this has wider implications than just in industry and business.
FAIR, which stands for Findable, Accessible, Interoperable, Reusable, is an essential framework for the future of analytical data. Tony has taken the opportunity of a recent conference in Amsterdam to update readers on FAIR and how it affects spectroscopic data.
This column explores the initial results extracted from the survey in the last issue into the training the next generation of colleagues currently receives in analytical chemistry.
Do you educate students who may go on to work in industry, or are you involved in assimilating students into your team? If so, you will really want to read this issue’s Tony Davies Column. Tony and co-authors, Jennipher Dania and Joachim Zahradnik, are undertaking two surveys to explore this area: one for Academics and one for Industrialists. Please do spend the very short time needed to complete one (or both) of these surveys.
Significant research is underway globally into both improving corrosion protection as well as removing chemicals of concern from existing corrosion protection coatings. This is because the cost of corrosion in developed economies has been consistently shown to lie in the range 2–4% of Gross National Product.
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”.
It is your turn to contribute: to the potential development of new spectroscopic instrumentation! Tony argues that many spectroscopic fields have seen little real development: and there are many reasons for that. Now, you have your chance to let us and, more importantly, the instrument vendors know what innovations (hardware and software) you would like to see in order to help you in your work. There is a short (three-question) survey ; please use this opportunity to help influence the future of the instrumentation you will be using.
