Short summary
Natural organic matter (NOM) is often studied via Fourier transform mass spectrometry (FTMS), which identifies organic molecules as mass spectra peaks. The intensity of peaks is data that is often discarded due to technical concerns. We review the theory behind these concerns and show they are supported empirically. However, simulations show that ecological analyses of NOM data that include FTMS peak intensities are often valid. This opens a path for robust use of FTMS peak intensities for NOM.
