As concerns about the quality of water and air continue to grow, easy on-site measurements that are as trustworthy as extensive laboratory results are necessary for the accurate assessment of both environmental compartments. That is precisely the focus of the Field Analytical Chemistry Group, which is part of the Department Monitoring and Exploration Technologies at the Helmholtz-Centre for Environmental Research (UFZ). The team is led by Dr. habil. Helko Borsdorf.
In our group, we combine knowledge from analytical chemistry, process engineering and electrical engineering to develop tailor-made analytical solutions for field applications, which provide reliable and credible analytical results. By enabling precise on-site quantification and characterization of organic compounds in water and air, we aim to enhance the long-term monitoring of water and air quality. Consequently, we use our knowledge in real-world-oriented, interdisciplinary research projects both within the UFZ and together with partners from industry and academia.
Our technical developments are comprehensively validated using special in-house developed inlet systems. This enables us to generate reference gases with adjustable, realistic concentrations of one or more compounds at various environmental parameters (e.g. humidity, temperature, ozone concentration, additional matrix compounds) and process parameters (e.g. flow velocity and turbulences along the sensor surfaces). In addition, we use gold-standard laboratory devices to investigate and understand environmental processes, for which we develop sensor solutions, and validate our sensor results. Finally, we apply both chemical sensing and analytical chemistry approaches for on-site investigations.
One of our applications is the investigation of the dynamics of biogenic volatile organic compounds (BVOCs) at forest sites. On the one hand, we aim to investigate the influence of external events such as heat waves or forest pests on the emission patterns of tree-related compounds. On the other hand, we want to understand how BVOC emissions are influenced by the current forest conversion in times of climate change. Due to high diurnal and seasonal variations in BVOC concentrations and environmental parameters, both these questions require long-term investigations at diverse forest locations. The integration into national and international networks enables us to conduct extensive measurements at field sites like Hohes Holz (TERENO), Tharandter Wald (ICOS) and the SMEAR II station at the Hyytiälä Forestry Field Station (eLTER). By having access to complementary data and comparisons with different methods for the analysis of BVOCs, we are able to verify the accuracy of our developments and improve them further.
