Welcome to the May issue of EVISA's Speciation Newsletter !
Atomic spectrometric techniques provide major tools for speciation analysis. Especially Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) is the work horse for trace element speciation analysis. Sample introduction is considered to be the Achilles' heel of atomic spectrometry. This is even more so for atomic spectrometry used for speciation analysis, since sample introduction is the interface between the separation technique used to differentiate the species and the detectíon by the atomic spectrometer. While the common sample introduction system for ICP-MS consists of a pneumatic nebulizer sitting in a spraychamber, providing relatively poor sample transport efficiency, researchers have also investigated other techniques to improve such drawbacks. Chemical vapor generation (CVG) is an important sample introduction technique, and is widely used for atomic spectrometry for its enhanced sensitivity and selectivity. Within our "Brief summaries" on techniques and methodology for speciation analysis we discuss whether vapor generation is also a good choice for speciation analysis (see the news below).
Dissolved organic matter (DOM) play an important role for the biogeochemical cycling of elements by controling the solubility, reactivity, and bioavailability of trace metals in soil and aquatic systems. Unfortunately, the mechanisms that govern the metal-binding properties of DOM remain only poorly understood, mainly because of the complexity of DOM. A group of U.S. scientists have now developed a quantitative method for the determination of metal complexes with dissolved organic matter (DOM) in the environment. The authors are convinced that their method provides an analytical foundation for advancing our understanding of trace metal biogeochemistry (see the news below).

EVISA is keeping you updated with what is going on in speciation analysis. In this section you will find news about the most current research results, about trends, legal issues and information from manufacturers in the field of speciation analysis.
Unfortunately, this month we have not seen any publication related to speciation analysis of general interest. In case that you feel that we missed something, we would be happy to receive a notification.
With all the links to further information and publications the News archive is a valuable collection of "hot topics" in speciation analysis. We continuously update even former news with new links and information so that all news are actual all the time.
Determination of Unknown Organic-Metal Complexes in the Environment by Liquid Chromatography–Inductively Coupled Plasma-Mass Spectrometry
A group of U.S. scientists have developed a quantitative method for the determination of metal complexes with dissolved organic matter (DOM) in the environment. The method is using an LC-ICP-MS approach with gradient compensation for providing consistent sensitivity over the whole chromatographic separation.

Chemical vapor generation as a sample introduction technique for speciation analysis
There are several techniques for speciation analysis that rely on elemental detection using atomic spectrometry, along with a separation technique to differentiate between different species. For liquid samples, liquid chromatography is the most commonly applied separation technique, while Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is the most frequently used detection method. However, the conventional sample introduction system for ICP-MS, which involves a pneumatic nebulizer in a spraychamber, results in poor sample transfer efficiency.
