ABSTRACT:
There is disclosed a time-of-flight (TOF) mass spectrometer capable of making a spectral measurement quickly and efficiently and making effective use of ionized samples. The instrument has a pulse-generating portion for producing appropriate pulse sequences. An arithmetic unit Fourier-transforms a resultant spectrum from a detector to find W(.omega.). The arithmetic unit Fourier-transforms a pulse sequence signal from the pulse-generating portion to find H(.omega.). The arithmetic unit calculates Y(.omega.)=W(.omega.)/H(.omega.) and takes the inverse Fourier transform of the calculated Y(.omega.).
