Time-of-flight mass spectrometer and mass spectrometric method using same

摘要

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 ).
