Welcome to the September issue of EVISA's Speciation Newsletter !
Inductively Coupled Plasma Mass Spectrometry (ICP-MS) in combination with a separation technique is the work horse for speciation analysis. The ICP-MS provides an ionization energy of 15.76 eV (the first ionization potential of argon), that is sufficient to substantially ionize most elements having an ionization potential below 10 eV. Elements with ionization potental approaching 10 eV (Zn, As, Se) or even surpassing 10 eV (C, P, S,I, Br, Cl) are only ionized to smaler degree (5% vor Br). The lower ionization degree directly translates in poorer detection power, making the detection of nonmetals (C, P, S) and halogens challenging (I, Br, Cl) or even impossible (F).
Since the detection power depends on sensitivity and signal/noise level, one way to improve the detection power is to the reduce the background and spectral interferences. In this way the introduction of tandem mass spectrometry with ICP-TQ-MS has improved the situation for otherwise challenging elements.
Last month we featured the speciation analysis of iodine, this month we have the speciation of chlorine in the news (see below). To make it even more challenging, the sample matrix discussed is not aqueous but organic.
Researchers from the French Institute IFPEN have developed a method based on the hyphenated technique GC-ICP-MS/MS for the determination of volatile organochlorides in complex hydrocarbon samples. Even under these challenging conditions, impressive limits of quantification below 100 µg Cl/L were obtained.

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.

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
Postdoctoral
DTU Food, Denmark: Analytical Food Chemistry
If you are passionate about analytical chemistry and interested in further developing your skills in method development and validation, this postdoc position is the perfect opportunity for you. DTU Food invites applications for a postdoc position with particular focus on the analysis of elements and nitrogenous compounds in food and feed. A major part of your work will be within the European Union reference laboratory for metals and nitrogenous compounds in food and feed (EURL-MN), which is hosted by DTU Food (www.eurl-mn.eu).
