Title: TIME-OF-FLIGHT MEASUREMENT-TYPE MASS SPECTROMETER DEVICE AND METHOD
Abstract:
A time-of-flight measurement-type mass-measuring device for accelerating ions stored in a first ion trap and introducing the ions into a flight tube to measure time-of-fight and thereby measure the mass of the ions, wherein the device is provided with: a second ion trap that is capable of storing ions to be measured and introducing the ions into the first ion trap; and a third ion trap that is capable of storing reference ions and introducing the reference ions into the first ion trap. The device is furthermore preferably provided with a control means for alternately performing in a prescribed pattern (e.g., once each): (1) introduction of the ions to be measured from the second ion trap to the first ion trap, and time-of-flight measurement of the ions to be measured; and (2) introduction of the reference ions from the third ion trap to the first ion trap, and time-of-flight measurement of the reference ions.
