Fourier transform ion cyclotron resonance mass spectrometry offers the highest mass resolution and mass accuracy for compositional analysis of complex organic mixtures, notably petroleum and its products.  This talk will describe several recent advances that extend FT-ICR figures of merit by an order of magnitude: phase correction; three-term segmented mass calibration; distributed post-excitation ICR radius; ion funnels; programmed ion injection; dynamically harmonized ICR cell with 120 degree excitation and detection and segmented end caps; conditional signal averaging; and mass spectral segment extraction.  The result is nonpareil performance for oil spill analysis.
