Tony (A.M.C.) Davies is again telling us to “Always look at the spectrum”. This time he uses an example from the development of a NIR spectrometer to demonstrate that one doesn’t really know what’s going on until one has “looked at the spectrum”.
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 (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.
Tony (A.N.) Davies is impressed with the service form the UK's EPSRC National Mass Spectrometry Service Centre.
Anaerobic digestion is a good solution to the joint problems of dealing with organic waste and producing “clean” energy. However, running the digesters at optimum performace is a complex business. NIR spectroscopy offers a solution to monitor a number of analytes within the reactor and in real time.
Tony (A.M.C.) Davies stresses the importance of always looking at the spectrum, even if you [think you] know there’s nothing to learn. He relates his experience with noise in NIR spectra and what he has learnt from it. He would like us all to examine spectra for abnormality before relying on automated methods.
1H NMR spectra are usually interpreted by hand, which is very time consuming, and can become a process bottleneck in fields such as high-throughput NMR. Greater automation of the spectral analysis process has become essential if NMR is to be of value as a high-throughput analytical method in the future.
