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.
In situ collection of volatile silver species in a new modular quartz tube atomizer for atomic absorption spectrometry
Stanislav Musil, Jan Kratzer, Miloslav Vobecký and Tomáš Matoušek

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
Evaluation of colloidal silicagels for lead isotopic measurements using thermal ionisation mass spectrometry

These two cover articles will be free to read for 6 weeks, so click through and take a look.
We have a tutorial review from Douglas C. Baxter, Ilia Rodushkin and Emma Engström from ALS Scandinavia in Sweden who looked at the fundamental aspects of isotope abundance ratio measurements by ICP-SFMS.

We also have a number of HOT articles in this month’s issue on topics as varied as crude oil analysis, neodymium isotopes, and environmental sample analysis. These papers will be free to read for 2 weeks.
