The high resolution mass spectrometry facility will enable novel comprehensive and accurate mapping of chemical fingerprints of trace-level organic compounds in environmental samples from laboratory and field studies. Combined with novel data mining tools, this will give detailed information on chemical composition, as well as putative identification of compounds.


Detailed chemical information provides in-depth molecular-level understanding of environmental processes. This is essential for advancing knowledge of societal challenges such as air pollution, climate change and sustainable food production, to improve parametrization in models and develop solutions of broad impact.


The new mass spectrometer facility is used to study chemistry of processes involved in formation of atmospheric aerosols, relevant for cloud formation and climate. The facility will also enable comprehensive understanding of molecular-level effects of climate change in the marine Arctic environment. Finally it will provide in-depth chemical knowledge of plant-microbe interactions in soil.
