This work builds on our previous study of arsenic species in apple juice1 by incorporating several improvements to the methodology and exploring the analysis more deeply.
The use of inductively coupled plasma mass spectrometry to quantify chemical hazards in natural history collections: arsenic and mercury in taxidermy bird specimens
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.
Sotiris Stasinos and Ioannis Zabetakis have used ICP-MS to investigate the cross-contamination of food crops by heavy metals in ground or irrigation water. They show that this can occur easily in certain crops, which has serious health consequences for those consuming the food crop. As a consequence of their work, the European Food Safety Authority (EFSA) has been informed about the accumulation of Cr and Ni in food tubers and is taking action.
An ICP-MS which offers improved performance and increased throughput to cut analysis times. It features a new interface and advanced technology that enables “one-click” set-up and easier routine maintenance. The ion-focusing system delivers high signal-to-noise performance and the Qcell with flatapole technology for low mass cut-off offers increased interference removal. Qtegra software fully automates the system.

Customers will benefit from our ability to get products to market faster, as well as to better align our offering with market needs."
The U-Series is a new style of glass concentric nebuliser from Glass Expansion. It provides improved performance and is very simple to use. The main benefits are that the sample channel is uniform from the entry point to the tip, which helpsavoid blockages; since there is nowhere for sample to be trapped, washout time is reduced and sample throughput increased; the VitriCone construction incorporates a precision-machined heavy glass capillary which resists vibration and delivers precision; Glass Expansion’s proprietary UniFit sample connector provides a simple connection with no dead volume. The U-Series is compatible with all ICP-OES and ICP-MS models.
The European Commission has cleared, under the EU Merger Regulation, the proposed acquisition of Varian Inc. by Agilent Technologies Inc., both US companies, by way of purchase of shares. The decision is conditional upon the divestment of Agilent's entire micro/portable gas chromatography instrument business and Varian's entire laboratory gas chromatography, triple quadrupole gas chromatography-mass spectrometry and inductively coupled plasma-mass spectrometry instrument businesses. In view of the remedies proposed, the Commission has concluded that the operation would not significantly impede effective competition in the European Economic Area (EEA) or any substantial part of it.

Inductively coupled plasma-mass spectrometry (ICP-MS) was introduced commercially in 1983 as a very sensitive analytical technique to be deployed for (ultra)trace element analysis. Compared to the previously existing techniques of atomic absorption spectrometry (AAS) and ICP-optical emission spectrometry (ICP-OES), the main advantages offered by ICP-MS over these techniques were its pronounced multi-element capabilities and substantially higher detection power, respectively.
