Producing absorption mode Fourier transform ion cyclotron resonance mass spectra with non-quadratic phase correction functions

摘要

RATIONALE: Previously described methods for producing absorption mode Fourier transform ion cyclotron resonance (FTICR) mass spectra have all relied on the phase correction function being quadratic. This assumption has been found to be invalid for some instruments and spectra and so it has not been possible to produce absorption mode spectra for these cases.
