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”.

Opportunities

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.
