It includes a laser unit for irradiating a sample with a beam of laser light and controlling the irradiation spot of the laser beam on the sample; and a mass analyzer for performing a mass analysis of the ions generated at the irradiation spot, where the mass analyzer uses a frequency-driven ion trap and a time-of-flight mass spectrometer to carry out the mass analysis. The ion trap of this system assuredly traps ions having large mass to charge ratios, and enables the system to carry out analyses on samples of large molecules. Preferably, a digital driving method is used to drive the aforementioned frequency-driven ion trap. Also, a multi-turn time-of-flight mass spectrometer may preferably be used as the aforementioned time-of-flight mass spectrometer.

摘要： The present invention provides a time of flight mass spectrometer having a spiral flight path, whose mass resolution can be appropriately changed with respect to the analysis object or other factor without any complicated alteration or addition of the mechanical construction. In a specific form of the invention, the mass spectrometer includes deflecting electrodes 20-23 located between semi-cylindrical electrodes 11 and 12 for making ions fly along a spiral path. The deflecting electrodes 20-23 generate deflecting electric fields for shifting the ions in the axial direction of the semi-cylindrical electrodes 11 and 12. The voltage applied to the deflecting electrodes 20-23 is changed according to the mass resolution required. The deflecting electric fields are generated or removed with the change of the voltage, which makes the ions fly either along a spiral path or in the same loop orbit. The flight distance of the ions can be controlled as desired by regulating the voltage so that the ions fly in the loop orbit an appropriate number of times. Thus, the mass resolution can be arbitrarily controlled.

摘要： A time of flight type mass spectrometer (TOF-MS) of the present invention includes: a flight space containing a loop orbit on which ions fly once or more than once; a flight controller for making ions of a same mass to charge ratio fly the loop orbit at several values of number of turns; a flight time measurer for measuring a length of flight time of the ions; and a processor for determining the mass to charge ratio of the ions based on a relationship between the value of number of turns and the length of flight time of the ions. The speed of ions flying a loop orbit depends on their mass to charge ratios. For ions of the same mass to charge ratio, the difference between the lengths of flight time of the ions flying the loop orbit N turns and of the ions flying the loop orbit N+1 turns depends on the speed of the ions, so that the difference depends on the mass to charge ratio of the ions. The difference in the length of flight time is unrelated to the variation in the starting time (jitter), variation in the detection timing (jitter), etc, so that the value of the mass to charge ratio can be precisely determined free from errors caused by such disturbing factors.
