Welcome to the September issue of EVISA's Speciation Newsletter !
The hyphenated technique HPLC-ICP-MS is the most often used technique for speciation analysis. The detection system ICP-MS provides high sensitivity for a broad range of elements combined with the possibility to evaluate isotope ratios. Since the ICP is destroying the molecules, speciation information however is lost. For this reason, information about the different species has to be provided by separation of the species by the HPLC system. The destruction of the molecules has also one positive effect: in general, the elemental sensitivity is not influenced by the species present in the sample. This effect allows for compound independent calibration (CIC) making elemental quantification of even unknown species possible. However, CIC can only be achieved when different species are measured under the same plasma conditions. When using HPLC for sample introduction, separation of different components may lead to changing plasma conditions during the chromatographic run. This is especially the case when using gradient elution conditions. Also signal intensity might be changing over long time periods as observed when performing chromatography. Researchers from LGC Ltd. (UK) now have developed a calibration method that can correct for on-column analyte losses and signal drift and can be applied with any detection system capable of recording transient signals (see the news below).
Speciation analysis by HPLC-ICP-MS can only be used for the analysis of liquid samples. Solid samples have to be extracted. Extraction efficiency is a real problem for speciation analysis, especially when species are strongly bound to the sample matrix, calling for relative harsh conditions for extraction that might degrade the species to be extracted. Researchers from Germany and France have now developed a strategy to gain species information even when species are degraded during extraction. The researchers used the approach to gain information about the gadolinium species retained in bone matrix after application of MRI contrast agents (see the news below).
The holiday season is finished and conferences and symposia are ahead. Indeed, some conferences scheduled for September and later of the year are foreseen as meetings with personal presence. EVISA's Agenda of Events is frequently updated in order to keep you informed about the organization of relevant events.

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.
New Strategy for Speciation Analysis of Gadolinium retained in Bone after Application of MR Contrast Agents
Researchers from Germany and France have developed a strategy to obtain information about gadolinium species that degrade during extraction from bone tissue.

On-column internal standardisation as an alternative calibration strategy for speciation analysis
Researchers from LGC Ltd. (UK) developed a calibration method for speciation analysis using chromatographic separation that can correct for on-column analyte losses and signal drift and can be applied with any detector capable of recording time-resolved data, provided that enough species resolution can be achieved.
