Both MALDI and ESI are well-known ionization method which have been worthy of remark among mass spectrometrists. FTMS is a mass analyzer which can be used for each ionization method with very high mass resolving power and mass accuracy. Here we introduce some MALDI/FTMS and ESI/FTMS spectra with the new topics among the FTMS users. The new topics include SORI (Sustained Off-Resonance Irradiation) and QE (Quadrupolar Excitation) techniques.

Key words: FTMS, FTICR, MALDI, ESI, QE, Quadrupolar excitation, SORI, Sustained off-resonance irradiation
