Organic environmental analysis is concerned with the development and application of chromatographic separation techniques, such as gas or liquid chromatography coupled with various sampling methods and detection techniques such as mass spectrometry. Here, the classical target analysis, i.e. the use and modification of already existing standard methods is needed for the investigation of various environmental compartments. Our particular expertise is the development of chromatographic reference methods for the analysis of environmental samples in order to achieve high precision and traceable result with low measurement uncertainty. This is essential to establish reference values in national and international interlaboratory comparisons and proficiency tests as well as for the certification of reference materials. In terms of non-target analysis strategies are developed and provided, which allow the characterization of transformation products and metabolites of known environmental pollutants.
