Issue 3 of Analytical Methods is now available for you to browse.
We take you to Germany and Brazil on this month’s covers: transport across cell monolayers studied by SECM, and the determination of mercury in soil by CVG-ICP-MS.
The front cover features a paper from our web theme on Future Electroanalytical Developments, a collaborative effort with our sister journal, Analyst. Frank-Michael Matysik and co-workers from the University of Regensberg, Germany, have used scanning electrochemical microscopy (SECM) for time-resolved studies of passive transport of redox active substances across cell monolayers with sub-cellular resolution. They say that the experimental approach presented in this study is an attractive alternative to conventional methods using Ussing-type chambers and opens new perspectives for studies of diffusion of substances through cell monolayers with single-cell resolution.

Our colourful inside front cover highlights work from Erico Flores of Universidade Federal de Santa Maria, Brazil, and his collaborators. They applied microwave-induced combustion (MIC) for mercury volatilization from soil with subsequent determination by cold vapor generation coupled with inductively coupled plasma mass spectrometry (CVG-ICP-MS). The authors say that their proposed method for soil decomposition combines safety and relatively high sample throughput, both of which are important aspects for routine trace analysis.
