Welcome to the July issue of EVISA's Speciation Newsletter!

This month we continue our series on brief summaries related to topics of speciatiopn analysis.  Speciation analysis calls for highly sensitive and selective detection. In general such characteristics are provided by hyphenated techniques combining a sensitive detection techniques such as ICP-MS with a selective separation techniques such as liquid chromatography. The on-line coupling is the preferred mode of operation, providing a closed system with reduced exposure to external contamination and supporting automation. However, also non-chromatographic separation techniques can be applied for cases of limited separation requirements (see the brief summary on non-chromatographic techniques below). Such limited separation power may be fit for purposes for cases where only two species or fractions have to be differentiated such as inorganic arsenic/organic arsenic, Cr(III)/Cr(VI), inorganic Hg/methyl mercury etc. (see the brief summary on types of species below).

The differentiation of inorganic mercury from methylmercury is of paramount importance, since methylmercury is a very potent neurotoxin. While humans are mainly exposed to methylmercury through the consumption of seafood, other sources cannot be ignored.  Researchers from the UK now investigated the exposure through rice. While the concentrations of mercury species in rice are much lower than in marine fish, the amounts of rice consumed are much higher resulting in exposure that cannot be ignored (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 informations from manufacturers in the field of speciation analysis.

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.

Methylmercury in European rice varies by more than a factor of 50
87 rice products sold in Europe, including baby-rice products, were analyzed for total mercury and methylmercury content. MeHg concentrations in all rice products studied range from 0.11 to 6.45 µg/kg.

Non-chromatographic separation techniques for speciation analysis
Non-chromatographic separation techniques have a low separation power and therefore can only be used for simple (mostly binary) separation such as As(III)/As(V) or fractionation !

Types of Chemical Species
The International Union for Pure and Applied Chemistry (IUPAC) has published guidelines or recommendations for the definition of speciation analysis. According to these definitions, chemical species are specific forms of an element defined as to isotopic composition, electronic or oxidation state, and/or complex or molecular structure.

With a list of about 50 current entries EVISA is informing you about interesting events and keeps you updated with their deadlines. By consulting our list of deadlines you won't miss the opportunity for early registration at reduced fee or the chance to submit your contribution in time.
