Tony Davies Column

The Tony Davies Column alternates between chemometrics and data handling and standards, as well as a wide range of EU and other initiatives across the whole of spectroscopy.

Tony-DaviesTony (A.N.) Davies has been a columnist for Spectroscopy Europe since its inception. Together with Tony (A.M.C.) Davies he has produced the “Tony Davies” column until Tony’s retirement in 2014. Tony (A.N.) is Lead Scientist with AkzoNobel RD&I Expert Capability Group in Measurement and Analytical Science in Deventer, The Netherlands and is Professor of Analytical Science at the University of South Wales in the UK.

TD-22_1-sChristmas is a time of giving and it is with great pleasure that we are able to report the news that Dr Michael Heise, a friend of many years both personally and of this column, has recently been awarded the title of Honorary Professor at the University of Applied Sciences of South-Westphalia in Iserlohn, Germany.1 Mike has been regarded for a long time as an “Internationaler Experte für Infrarot-Spektroskopie”, as the Iserlohn University of Applied Sciences put it on their press release!

Introduction

This column has been developed from two recent publications by Tom.1,2 My thanks to NIR Publications for allowing us to use Reference 1 essentially unchanged.

It is common practice in near infrared (NIR) calibration to apply pre-treatments designed to correct for the scatter effects usually seen in absorbance data. These pre-treatments can interfere with interpretation of the spectra. This is illustrated here with the aid of two rather extreme artificial examples.

OK... I know... for the majority of the readers of Spectroscopy Europe a phrase which comes from Yorkshire probably makes a pretty poor title for an article. However, if in “Where There’s Muck There’s Brass” you simply translate Muck as Dirt or Waste and understand that Brass is a Yorkshire term for Money, then you might get a little closer to our subject, Spectroscopy in Anaerobic Bioreactor Monitoring and Control.

At the Sustainable Environmental Research Centre (SERC), which has carried out research in AD systems for more than 30 years,1 we have initiated a new knowledge transfer organisation to help, advise and promote Anaerobic Digester technology. Led by Dr Sandra Esteves the AD centre has the explicit aim of helping early adopters overcome some of the common hurdles they may encounter (www.walesadcentre.org.uk).

Fans of “Monty Python’s Flying Circus” will realise that what follows is not likely to be my usual column (and they might be hoping that it will be amusing).

Introduction

This column is about “Computational Chemistry”.

I would like to thank everybody who has taken the trouble to respond to my last column on Educating Spectroscopists.1 I am very happy that Ian has allowed me space to reproduce some of them in this edition.
