PD Dr Thomas Letzel

// born 1970, studied chemistry (1992–1998) at the TU Muenchen and the LMU Muenchen

// He acquired his doctorate in 2001 with an environmental-analytical subject at the TU Muenchen, followed by a two years' postdoc stay at the Vrijen Universiteit Amsterdam

// He qualified as a professor at the TU Muenchen in 2009 and has since been teaching there as a senior lecturer

// He is the manager of the Analytical Research Group at the Chair of Urban Water Systems Engineering and is the project officer of TUM in the BMBF project RISK-IDENT in this function

// He has previously developed new analytical platforms and strategies for detection, identification and determination of functional properties of organic molecules from complex mixtures in different natural-sciences disciplines

// The results are mirrored in his more than 60 scientific publications and two books

OMI (Organic Molecule Identification) in water using LC-MS(/MS): Steps from “unknown” to “identified”: a contribution to the discussion

In a class of its own - von PD Dr Thomas Letzel, Thomas Lucke, Dr Wolfgang Schulz, Dr Manfred Sengl, Dr Marion Letzel

The analysis of small organic molecules in water is highly demanding,
on account of the presence of varia­bility in the water matrix (rain-, ground- and drinking water, plus ­surface and waste water) and the spectrum of chemical structures, present in a wide range of concentrations. In the Lab & More International, 2014, 1 (pp. 14–18), we introduced the water analysis methods of target screening, suspects screening and non-target screening,...

Non-target screening, suspected-target screening and target screening – of technologies and philosophies, databases and crafts

The three terms in the title, as well as “Known Unknowns” and “Unknown Unknowns” are new keywords that are currently con­fusing the analytical water scene. The procedure in use of just these ­technologies, however, often is not consistent yet. This article will now try to put the many different terms and approaches into some ­semblance of order. At the same time, it will report on pragmatic appli­cations.
