New method for organic mass spectrometry applied to original seawater analysis
We are very excited that we can now analyse dissolved organic matter (DOM) in original seawater using ultrahigh resolution mass spectrometry - 15 GB of data on organic compounds in 100 microlitres of water. In collaboration with Dr. Oliver Lechtenfeld’s group Dr. Oliver Lechtenfeld at the Helmholtz Centre for Environmental Research (UFZ Leipzig), we present a new method for DOM characterization, which allows direct injection of original (i.e., non-extracted), filtered ocean water samples at native salt and DOC concentrations.
To achieve this, we used reversed-phase liquid chromatography, enhanced by an isocratic elution step and a postcolumn counter gradient, hyphenated with Fourier transform ion cyclotron resonance mass spectrometry (LC-FT-ICR MS).
