A Strategy for the Determination of the Elemental Composition by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry Based on Isotopic Peak Ratios

We propose a novel strategy for determining the elemental composition of organic compounds using the peak ratio of isotopic fine structure observed by high-magnetic field Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). Using 3′-phosphoadenosine 5′-phosphosulfate and CTU guan...
