©2020 Biological and Chemical Oceanography Data Management Office.In Fourier Transform Ion Cyclotron Resonance Mass Spectrometry, the mass-to-charge ratio (m/z) of an ion is experimentally determined by measuring the frequency at which the ion processes in a magnetic field. These frequencies, which are typically in the 100 KHz to MHz regime, can be measured with modern electronics making it possible to determine the mass of an ion to within +/- 0.000005 amu or 5 ppm.

| DOM analysis by liquid chromatography 21T fourier transform ion cyclotron resonance mass spectrometry with filtered seawater collected during a Bermuda Atlantic Time Series cruise AE1912 aboard R/V Atlantic Explorer in June of 2019 | Samples were analyzed by 21 Tesla Fourier Transform Ion Cyclotron Resonance Mass Spectrometer coupled to a microflow high pressure chromatography system (Ultimate 3000 RSLCnano, Thermo Scientific). The 21 T FT-ICR MS was designed and built in the Environmental Molecular Sciences Laboratory at the Pacific Northwest National Laboratory 26. The ESIMS was equipped with a heated electrospray ionization source set to a capillary voltage of 3200 V, sheath, auxiliary, and sweep gas flow rates of 15, 3, and 1 (arbitrary units), ion transfer tube temperature of 300°C, vaporizer temperature of 75°C. Mass spectra were collected with 1.5 second transients with a maximum ion accumulation time of 250 ms in positive ionization mode. | Tesla Fourier Transform Ion Cyclotron Resonance Mass Spectrometer |
