Dear Reader !

Welcome to the October edition of the Speciation Newsletter provided by the European Virtual Institute for Speciation Analysis (EVISA).

The month started with the FACSS meeting and continues with the International Beijing Conference and the Hungarian-Italian Symposium on Spectrochemistry, both of them having a number of  contributions dedicated to speciation analysis.  

Instrumental development has reached a state enabling trace element determinations at the ppb and sub-ppb level. However, since speciation analysis is always looking for fractions of trace elements further development is required. ICP-MS is dominating the scene with respect to speciation analysis in the liquid phase, but other techniques should not be overlooked.  A development made at the University of Münster together with the German Company Gerstel  shows an alternative for a less costly detection system (see our News section).

Speciation analysis is enabling species determinations at trace levels as found in real systems and organisms empowering biochemists, toxicologist, nutritional scientists and others health related scientists to study biological effects and metabolic pathways of trace element species.  Selenium-proteins seem to play a major role in many biological functions making selenium an essential trace element for animals and humans. A new study shows that selenomethionine is a promising agent protecting against esophageal cancer (see our News section).  Because of such promising health effects some people believe in the beneficial effect of additional Se-supplementation. It's good to learn from a new study of the analytical research group at the University of Graz that contributes to the understanding of the metabolism of selenium compounds in the human body (see the News), that excessive selenium is excreted in a non-toxic form.

We hope that our newsletter will attract your interest, and would be happy to receive your suggestions, comments or criticism.


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 informations from manufacturers in the field of speciation analysis.

New light on human selenium metabolism
The analytical research group at the University of Graz has presented new results of a selenium speciation analysis on human urine from one volunteer over a 48-hour period after ingestion of 1.0 mg of selenium in three different forms in the recent issue of "Analytical and Bioanalytical Chemistry".

University of Münster: Industrial Cooperation on Mercury Speciation
The Department of Applied Atomic Spectroscopy / Innovative Analytical Instrumentation at the Institute for Inorganic and Analytical Chemistry of the University of Muenster (Germany) and the German company GERSTEL GmbH & Co.KG, Mülheim have developed a new detection system for elemental speciation by GC-PED.

Two new Thio-Arsenosugars found in Scallops
As part of an ongoing project investigating arsenic species in food products, the research group from the University of Graz scanned several mollusc samples from the local fish market for thio-arsenosugars using HPLC-ICPMS under conditions optimized for detection of these arsenicals. Two novel thio-arsenosugars were identified in aqueous and methanol extracts from the gonad and the muscle of the great scallop. Due to their unusual chromatographic properties, these compounds are difficult to detect by existing methods. To overcome these difficulties, the research group developed a new method based on HPLC-ESMS.

Selenomethionine shows promising results as a protective agent against Esophageal Cancer
Selenomethionine treatment of certain high-risk patients show promise as protection against the development of esophageal squamous cell cancer (ESCC), according to a report in the September issue of Gastroenterology.
