Dissolved organic matter (DOM) consists of various complex structures, thousands or even millions of different molecules. The identification of the isomeric structure of each molecule is still far from any instrumental analytical realization [1]. The highest analytical resolution of DOM, which is the elemental composition of components, can be achieved by Fourier transform ion cyclotron resonance mass spectrometry (FTICR‐MS) [2–5]. Nevertheless with the high resolution attempts it can be possible to identify aquatic biogeochemical processes by investigating water samples as function of time and/or space. In the case of water body monitoring as function of depth and season or time rather small abundance variations can be expected due to mixing effects of the water body.
