Parts-Per-Billion Fourier Transform Ion Cyclotron Resonance Mass Measurement Accuracy with a “Walking” Calibration Equation

Ion cyclotron resonance frequency, f, is conventionally converted to ion mass-to-charge ratio, m/z (mass “calibration”) by fitting experimental data spanning the entire detected m/z range to the relation, m/z = A/f + B/f 2, to yield rms mass error as low as ∼200 ppb for ∼10 000 resolved components o...
