Natural organic matter as complex biogeochemical non‐repetitive material was investigated with ion mobility mass spectrometry (IMS) and ultra‐high‐resolution Fourier transform ion cyclotron resonance mass spectrometry (FTICR‐MS) approaches in order to unravel the existence of multiply charged state constituents. Hereby we describe and assign the potential molecular formulae of these doubly charged species, derived from FTICR‐MS, and the existence of these species was confirmed via IMS. The parallel application of these powerful techniques enabled the boundaries of the understanding of natural organic matter to be pushed further. Copyright © 2009 John Wiley & Sons, Ltd.
