Speciation of selenium in yeast cells

Integrated microfluidic chip for selenium speciation

In this paper, researchers from the Whuan University in China present a new method for speciation of selenium in yeast cells.

Using on-chip magnetic solid phase extraction and high performance liquid chromatography (HPLC)-inductively plasma mass spectrometry (ICP-MS), Bin Hu and colleagues revealed that the amount of selenocysteine and selenomethionine in a single-enriched cell are in the order of picograms.
According to the authors, this new analytical method is sensitive, fast, low cost and easy to use.

Where does gold come from?

Direct analysis of geological and artefact gold is now possible thanks to a study published in JAAS.

Analysis of alluvial gold deposits from Ireland

Researchers from the University of Bristol in UK used solution and laser ablation mass spectrometry techniques to analyse lead isotopes in gold. They demonstrated the applicability of these techniques to archaeological samples by studying natural gold grains from two Irish alluvial gold deposits and two artefact samples from Early Bronze Age.

Currently, lead isotope analysis is the preferred method to establish the geographical origin of ore deposits, but when the study concerns the origin of gold mineralisation, analyses are performed on gold derived from the host rocks where it was originally formed. According to Christopher Standish and co-workers, this new approach allows direct analysis of both geological and artefact gold and improves the studies on archaeological provenance of gold used in antiquity.

To know more about this work, click on the link below. This paper will be free to read until January 24th.

Front cover: Bordel et al., J. Anal. At. Spectrom., 2012, 27, 1658

This month’s issue of JAAS is now online and ready for you to read. On the front cover is a very striking and colourful image from the group led by Nerea Bordel and JAAS Advisory Board member Jorge Pisonero at the University of Oviedo, Spain. Together with their team, they have developed a new experimental setup that can apply an intense and transverse magnetic field of up to 70 mT to radiofrequency glow discharge plasma for optical emission spectroscopy. This produces a magnetic field independent of the sample thickness. Read more about their work by clicking below.

JAAS Issue 9 now online

Musil et al., J. Anal. At. Spectrom., 2012, 27, 1382

This month’s issue of JAAS is now online for you to read. We have two interesting covers this month. On the outside front cover is an image from the Czech republic. Stanislav Musil and colleagues from The Institute of Analytical Chemistry of the ASCR, Brno, have successfully formed a collection of volatile silver species for the first time. This substantially improves the analytical performance of a previously reported on-line atomization procedure.

Huyskens et al., J. Anal. At. Spectrom., 2012, 27, 1439

On the inside we have an image from The Australian National University, Canberra, Australia. The analysis of Pb isotopes is used in several fields, including ore formation studies, environmental studies and U–Pb geochronology. But sample sizes can also be very small, making precise measurements difficult. One method to compensate for this, is adding silicagel as an ionisation activator for Pb isotopic analysis. Magdalena H. Huyskens, Tsuyoshi Iizuka and Yuri Amelin have run a series of tests, comparing three commercially available colloidal silicagels
