Dissolved organic matters (DOMs) is a complex mixture of degradation products from plants and animals and it plays a key role in the global carbon cycle. The ultra-high resolution mass spectrometer, such as Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS), is required to analyze DOMs in a river or ocean. Because the number of DOMs that exist in the mass spectrum is at least over 2000 peaks, an automatic analysis software is needed for the analysis of the numerous peaks of DOMs. Thus, we developed a software for the analysis of DOMs using a MATLAB language. In this study, we collected water samples of the Han River at Amsa located in the main stem and Jungnang located in the tributary. The collected water samples divided into two microtubes, and then one was treated C18 solid phase extraction (SPE) and the other was subjected to C18 SPE after microbal incubation for 5 days. Mass spectra were obtained by 15 T FT-ICR MS (SolariX XR, Bruker Daltonics, Germany) and various Van Krevelen diagrams were plotted using a home-coded MATLAB program. To conclude, the Han River of Amsa and Jungnang water samples were analyzed by a semi-automatic home-coded program, and a graphic user interface (GUI) will be added in the near future.
