In the Tony Davies 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 the “The analysis of poly aromatic compounds: a never-ending story?”, Peter Jenks reports from the 25th International Symposium on Poly Aromatic Compounds. He was disappointed to find the near total absence of mention of the use of CRMs in method development or as a calibration material. He concludes that “data from the academic and research community often acts as a stimulus for government concern and the data may ultimately may result in legislation. It concerns me that legislation may be driven by bad data”.
Kim Esbensen and Claas Wagner tackle the problem of heterogeneity in sampling and show how it can be dealt with at the primary sampling stage by “Composite sampling I: the Fundamental Sampling Principle”. As well as explaining the theory they also introduce practical solutions.

Jürgen Gross has been using ambient mass spectrometry to look at the presence of polydimethylsiloxanes (PDMS) in food prepared in silicone rubber objects and on baking parchment. He shows that PDMS migrates into the food, something perhaps we should think about if in the mood for some baking!
Stanislav Strekopytov tells us about “The use of inductively coupled plasma mass spectrometry to quantify chemical hazards in natural history collections: arsenic and mercury in taxidermy bird specimens”. It is quite shocking to learn about the use of poisons to preserve taxidermy specimens in the past. Nowadays it is essential that the dangers from such specimens are known before they can be handled by museum staff and particularly if they might be touched by visitors. ICP-MS analysis provides fully quantitative information on bulk contents of toxic elements in taxidermy specimens and so is well suited to this task.
Mark Tobin and colleagues describe “Fourier transform infrared spectroscopy and imaging of dragonfly, damselfly and cicada wing membranes”. Insects and plants have evolved highly specialised surfaces such as being highly water repellent or superhydrophobic, which also confers self cleaning properties. This is of interest to materials scientists to help in the development of manufactured materials with similar properties. High spatial resolution FT-IR spectroscopy and imaging provide useful information about the complex chemical patterning that contributes to this functionality.
In the Tony Davies Column, we learn about “Automated detection of counterfeit drugs using multimodal spectroscopy and advanced web-based software platforms”. With the increase in trafficking of counterfeit medicines and other products, there is a need for definitive results from an on-site analyser useable by customs officers. 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.
John Hammond updates us on “Reference materials: what’s new?”. The 2015 meeting of the ISO Committee on Reference Materials (ISO/REMCO) was held in June and significant developments in a number of standards that will ultimately affect all users of reference materials have taken place.
Kim Esbensen and Claas Wagner have gold on their minds. However, only to explain that “Sampling—is not gambling!”: the American “Gold Rush” of the late 19th Century is a good metaphor for the unrepresentative nature of grab sampling: something that you will soon realise is to be avoided in any sampling regime.
