摘要： The present invention relates to a data processing device for mass spectrometry, in which measurements are performed in a high dynamic range without causing an overrange in an A/D converter in any TOF scan. A data acquisition circuit of a mass spectrometer includes an amplitude value computing circuit which measures and stores a maximum amplitude value of an ion detection signal, a gain control circuit for determining and setting a gain amount for the next measurement, and others. From the immediately preceding TOF scan data or TOF scan data plural times before, the maximum amplitude value of the ion detection signal is extracted. Then, before the next TOF scan, an optimum gain amount is determined based on the extracted maximum amplitude value to adjust the gain of the input signal, and the ion signal is sampled in the A/D converter.

摘要： An ion trap time-of-flight mass spectrometer capable of obtaining highly-sensitive mass spectra even on the lower mass number side is realized. The ion trap time-of-flight mass spectrometer includes an ion source that operates at atmospheric pressure, an ion optical system for introducing the ions generated by the ion source into a vacuum chamber and converging the ions introduced into the vacuum chamber, an ion trap part for trapping ions in the vacuum chamber, a multipole part for converging the kinetic energy of the ions discharged from the ion trap, and a time-of-flight mass spectrometry part for measuring the ions discharged from the multipole part. The period of high-voltage pulses generated by an electrode provided in the time-of-flight mass spectrometry part can be changed depending on an ion content introduced into the multipole part.
