Welcome to the April issue of EVISA's Speciation Newsletter !
As we have discussed last month, ICP-MS is the most often used system for the determination of element species. While it provides outstanding sensitivity for many elements it cannot provide any selectivity for different species of the same element. For providing such selectivity, ICP-MS must be coupled with a separation technique. The technique providing the broadest application field is high-performance liquid chromatography (HPLC). This technique can be tuned to many separation problems by selecting an appropriate separation mode and provides a separation power sufficient for the separation of many species. The biggest challenge than comes from the target sample not being in the liquid phase, calling for an appropriate extraction procedure.
This is exactly the problem of selenium speciation in fortified vegetables. A group of Chinese researchers has now presented a method providing high extraction
yields and good detection power for five Se species being present in the vegetables (see the news below).
In case that the target species are limited to two, the high separation power of HPLC is not required and other non-chromatographic separation methods can be applied. This is often the case for species were the task is to differentiate the more oxidized species from the less oxidized one, such as Fe(II)/Fe(III), Cr(III)/Cr(VI) or Sb(III/Sb(V). A group of researchers from Spain and Brazil have developed a two-step
procedure for the speciation of inorganic antimony. The procedure is
fully automated by using a multisyringe flow injection manifold coupled
to ICP-MS allowing for the analysis of 30 samples per hour (see the news below).
The EVISA diary of events for the coming weeks is full of meetings scheduled to take place as on-side events. Let's hope that after such long time of absence we can meet each other and discuss face to face.

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.
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.
