Tony Davies and Steven Brown explore the solid-state nuclear magnetic resonance spectroscopy facilities at the University of Warwick, UK.
Kim Esbensen and Claas Wagner continue to stress that grab sampling is still an absolute no-no regardless of the size of the sampling device or the sample.
The study of metabolites in our sewage systems is not new, but there are particular difficulties with identifying the metabolites from new psychoactive substances, or “legal highs”. The authors describe a wide range of sample collection methodologies and their analysis with mass spectrometry.
This article gives a most useful overview of the analysis and sequencing of nucleic acids by matrix-assisted laser desorption/ionisation mass spectrometry, which should interest all readers and may well serve as a useful tutorial article.
There are a number of advantages of Raman microspectroscopy, including its the ease of its application, as in many cases no or very little sample preparation is needed and the experiments are performed at atmospheric pressure.
Lithium ion batteries power most of the electrical devices we rely on every day. As well as mobile phones, laptops and tablets, they are finding increasing use in vehicles, with electric cars not uncommon on our streets. This article is from a young scientist who has won help for her research through an instrument company’s support programme. You can find out more, read the article and even apply yourself.
International standards need to keep pace with the innovation in analytical equipment and practices. For example, many of the advances in nuclear magnetic resonance (NMR) spectroscopy reported in this journal in recent years have yet to find themselves mirrored by updates in the respective Recommendations of the International Union of Pure and Applied Chemistry (IUPAC), nor in the many and varied proprietary recommended reporting formats of the different peer-reviewed primary scientific journals. Not that every innovation needs to be “standardised”: with the speed of many developments it is important to find the right balance between reacting to real movements in a field and enshrining a short-lived fad in a IUPAC Recommendation.
This column now turns its attention to sampling using a very popular tool, the “sampling spear”. There is much good to be said about spear sampling—and only one thing which is bad. But this is bad enough: spear samplers are very, very difficult to get to produce representative samples! The spear sampling principle can be made representative, but in most practical situations in which spear sampling is used today it manifestly is not. WHY? And more importantly, WHAT can be done about it? This column also turns out to touch on one of TOS’ six governing principles: SSI, Sampling Scale Invariance.
