Colette Germon, Tony Davies and Paul Jones look at “Combining teaching chemometrics, with attenuated total reflection–infrared spectroscopy and food authentication”. They describe a teaching project based around the detection of food fraud. It is a good example of teaching spectroscopic data handling and advanced analysis techniques. They have investigated how adulteration and misrepresentation of meat and fish can be detected, as well as whether frozen and then thawed fish could be differentiated from chilled fish.

Developments in hardware, higher field instruments, better multinuclear probes including cryoprobe options, spectrometer control systems and also desktop NMR data processing software have all combined to make the measurement of inorganic nuclei a potentially commonplace and very helpful, often complementary, technique to other spectroscopic analytical tools.
Tony Davies and Robert Lancashire ask “How standard are your standards?”. They describe a number of the organisations working with standards that affect the spectroscopy field. It looks as if free access to these may be the only way to ensure their longevity.
Tony Davies and Steven Brown explore the solid-state nuclear magnetic resonance spectroscopy facilities at the University of Warwick, UK.
In this article, it is discussed why International standards need to keep pace with the innovation in analytical equipment and practices.
Tony Davies has interviewed Gerard (Gerry) Downey who has just retired from the Irish National Agriculture and Food Research Institute, Teagasc. Gerry will be known to many of you, particularly those who work in the fields of chemometrics, NIR spectroscopy and food & ag. I must have known Gerry for over 25 years and currently work closely with him on the publication of NIR news, so I am particularly delighted that Tony has chosen to highlight his career.
In the Tony Davies Column, Tony is getting jealous of chromatographers in “Central spectroscopic data systems: why are chromatographers so much better equipped?”. Replicating the power of chromatography data systems for spectroscopic data is not that easy.
“Spectroscopic data handling at petabyte scale” shows how one institute is dealing with truly huge amounts of data, both in its collection and in its distribution to scientists for interpretation and analysis. At the same time, the institute has been able to incorporate best practice around the FAIR Data Stewardship of scientific information.
In the Tony Davies Column, Tony looks at “Raman imaging of difficult surfaces”. He looks at a number of different approaches to dealing with uneven samples, as well as reviewing instrumental improvements that have made Raman imaging a viable analytical and diagnostic tool.
In this column, Tony describes “A new approach to identifying unknown trace level analytes by tandem mass spectrometry without reference spectroscopic database support: CSI:FingerID”. This allows for tandem mass spectrometry data to be used to identify unknown analytes from common molecular structure databases where reference spectroscopic data is unavailable.
In this Tony Davies Column, we learn about “Automated detection of counterfeit drugs using multimodal spectroscopy and advanced web-based software platforms”. The German authorities have commissioned the development of a multi-modal, transportable inspection system, including intelligent data processing and evaluation, for fast spectroscopic recognition of illicit drugs and counterfeit medicines. This is described in the column.
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.
Tony Davies and Mohan Cashyap are concerned about your NMR data. When an article starts “On 10 October 2014 the impossible happened”, you will want to take note! Following the withdrawal of Agilent from the NMR business, Tony and Mohan consider three solutions to ensuring your NMR data is available now and into the future. If you have an NMR of any make, you will want to read this. Do remember that you can comment on the web version of the article.
Following on from the two recent articles on how the Cloud may be impacting the availability of scientific software delivery for spectroscopists, this article looks at what the wider commercial spectroscopy software providers have been doing in this area.
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.
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...
Tony (A.M.C.) Davies continues on his last furlong, this time considering “Classification and identity testing”. As well as some interesting insights into the analytical lab in the late 1960s, he gives his opinion on various chemometric techniques and on identity testing, as well as thoughts on future development.
In the Tony Davies Column, Tony (A.N.) Davies and Mohan Cashyap introduce us to the potential for Cloud Computing in the lab. This is the first of a two-part contribution, and, for the second part, they need your help with your experiences of Cloud Computing in your lab or organisation.
Tony (A.M.C.) Davies looks at Multiple Linear Regression (MLR) this issue, as well as expressing his opinions about Principal Components Regression (PCR) and Partial Least-Squares (PLS).
Tony Davies explains “Terahertz Spectroscopy” and describes some new and interesting applications
