Notes:
In standard pulsed ion cyclotron resonance mass spectrometry (ICRMS) mass spectra are generated by converting the time domain signal to the frequency or mass domain by fast Fourier transform (FFT). The FFT requires long acquisition times to acquire high resolution mass spectra. In ICRMS, long acquisition times introduce distortions in the peak intensities of the transformed spectrum that lead to errors in ion abundance. We report here the use of linear prediction methods on data sets collected during much shorter acquisition times to determine actual ion abundances more accurately.
