We have two covers in this latest issue of JAAS and they will both be free to read for 6 weeks. On the outside front cover is work from Christophe Quetel and colleagues at the EC – Joint Research Centre – Institute for Reference Materials and Measurements in Belgium. They have been testing the limits of strontium isotope ration measurements using MC-ICPMS.
Isotope ratio measurements by MC-ICPMS below 10 μL min−1 under continuous sample flow conditions. Exploring the limits with strontium
E. Paredes, D. Goitom Asfaha and C. R. Quétel

On the inside front cover we have an image from Wuhan University, China, where Bin Hu and colleagues have been looking at the speciation of selenium in cells. This type of elemental speciation work is important for metallomics research.
Speciation of selenium in cells by HPLC-ICP-MS after (on-chip) magnetic solid phase extraction
Beibei Chen, Bin Hu, Man He, Qian Huang, Yuan Zhang and Xing Zhang

We also have a couple of HOT articles for you to read. Both will be free to access until Feb 28th.
JAAS Editorial Board member Gary Hieftje and co-workers at Indiana University USA, have a paper where schlieren imaging and infrared (IR) thermography were utilized to visualize plasma-gas flow and heat transfer, respectively, from a pin-to-capillary geometry flowing atmospheric-pressure afterglow (FAPA) ambient ionization source.
Visualization of mass transport and heat transfer in the FAPA ambient ionization source
Kevin P. Pfeuffer, Jacob T. Shelley, Steven J. Ray and Gary M. Hieftje

And from Jan Kratzer, at the Institute of Analytical Chemistry of the ASCR, Czech Republic, has together with co-workers investigated plumbane generation and subsequent preconcentration of lead species on quartz surface using radiometry and autoradiography.
Hydride generation – in-atomizer collection of Pb in quartz tube atomizers for atomic absorption spectrometry – a 212Pb radiotracer study
