Dear Subscriber !
Welcome to the November issue of EVISA's Speciation
Newsletter.
Metallomics is a subject that is receiving great attention as a new frontier in the investigation of trace elements in biology and is expected to develop as an interdisciplinary science complementary to genomics and proteomics.
Szpunar (2005) defined metallomics as "comprehensive analysis of the entirety of metal and metalloid species within a cell or tissue type". Obviously, speciation analysis is a tool suitable to study the metallome. Recently scientists have found that the abundance of metallic species within the proteome is much higher than previously thought (see the EVISA News from July 22, 2010). Almost half of all enzymes must associate with a particular metal to function. An ambition is to understand why each metal–protein partnership arose and how it is maintained. Highly interdisciplinary science will hopefully help to answer such questions. Scientists being active in that field will meet next year in June 15-18 in Münster, Germany for the Third International Symposium on Metallomics. An attractive program consisting of invited lectures, contributed presentations, posters and an exhibition will provide an overview about the state-of-the-art. Please feel invited to join us for this stimulating event. The call for papers is open now !

NEWS
|
|
|
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.
Registrations pick up as REACH deadline looms
The number of substances registered under the REACH chemicals legislation is rapidly increasing as the first registration deadline of 30 November approaches. The deadline is for substances produced or imported in large volume or those that are toxic.

NEW PRODUCTS

PerkinElmer NexIONTM 300 ICP-MS with Chromera® II software and automated switching valve.
The new PerkinElmer NexIONTM 300 ICP-MS with the new Chromera II speciation software provides seamless integration between ICP-MS and chromatography systems. In addition it takes the automation of speciation a step further, with an automated switching valve linking the chromatography system to the NexION 300 ICP-MS. The switching valve allows the NexION 300 ICP-MS to warm up and be optimized while at the same time equilibrating the column with mobile phase. The software can also control a second switching valve which can be used to add online internal standards, isotopically labeled internal standards, or allow post column reactions.
Figure 1. The switching valve finally automates all steps of speciation.
The simplest and most streamlined operator experience ensures maximum efficiency and optimizes workflow.
The PerkinElmer NexION 300 ICP-MS can be easily integrated with liquid chromatography (LC), gas chromatography (GC) and ion chromatography (IC) systems to deliver a complete bench solution for the separation and determination of individual metal compounds.
Fastest data acquisition speed. Due to the extremely fast mass spectrometer and detector, the NexION 300 can record over 3000 data points per second allowing great resolution on transient peaks, even if you are monitoring several isotopes on narrow peaks.

EVISA provides information about open positions for Ph.D. students, PostDocs and permanent staff in the field of speciation. Looking to fill a vacancy or needing a new career challenge? Either way this service is FREE. Many laboratories and research facilities (from Greenland to Crete) have already found their highly educated stuff through this service by EVISA. If you would like to post an open position here, please contact us at info@speciation.net !
Doctorates
Helmholtz Zentrum Muenchen; Short Term Marie Curie Fellowships for PhD students in Environmental Chemistry
Investigation of the influence of chemical speciation on the accuracy of QSPR/QSAR models:
The biological activity and fate properties of chemicals can drastically change depending on whether ionic or neutral forms of molecules are present in the environment. The difficulties with this task are frequently connected to low accuracy of existing methods to predict dissociation constants of molecules. The pKa model or otherwise calculated dissociation constants and/or experimental dissociation constants of molecules will be used to address this question and explore whether use of chemical speciation can increase accuracy of QSPR / QSAR models.

University of Liverpool: Iron speciation and humic substances in seawater
It is proposed that the student in this project makes a detailed study of the chemical speciation of iron and the concentration of iron-binding HS. Previous work has demonstrated the presence these ligands in Liverpool Bay and the Irish Sea. We will now concentrate on the estuary of the Mersey as a source of these ligands. The work may be extended to the Irish Sea. Samples will be collected during cruises with the University research vessel or the Environment Agency.
