摘要： An numerical analysis time which is assigned to mass select one ion species having a specific mass-to-charge ratio mass selected is divided into the first part time and the second part time, and a dipole auxiliary electric field capable of spatially reducing a spread is superimposed in the first part time of the numerical analysis time and a quadrupole auxiliary voltage capable of rapidly emitting ions when position coordinates are large is superimposed in the second part of the time. Therefore, the initial spatial spread is reduced in the first part time and the trajectories of ions is rapidly amplified in the second part time, and the ions are emitted. Thus, the entire mass sweep time can be reduced and a high-resolution numerical analysis can be accelerated.

摘要： By preventing the trapping efficiency of ions from largely depending on the mass-to-charge ratio, an ion trap mass spectrometer suitable for obtaining a high sensitive mass spectrum is provided. Ions of a specimen to be mass analyzed generated at an external ion source pass through an ion transportation portion and then injected into a space (ion trap volume) between the ring electrode and the end cap electrodes. An RF trap voltage power source applies an RF frequency V.multidot.cos .OMEGA.t between the ring electrode and the end cap electrodes to form a radio frequency electric field in the ion trap volume. The RF trap voltage is changed so that the optimum trap frequency is in inverse proportion to 1/2 power of a mass-to-charge ratio while the ions are being trapped in the radio frequency electric field formed in the ion trap volume.

摘要： A mass spectrometer and a mass spectrometry method having a high ion selection efficiency are provided. The mass spectrometer comprises an ion trap, a sample introducing device, an electron gun, a detector, a power supply for applying voltage to the ion trap, a control device for controlling the power supply and the electron gun, a mass analyzing device for performing mass spectrometry based on a detected signal of the detector. Using an auxiliary power supply, direction of an auxiliary electric field generated between end cap electrodes is made to point only toward the detector. In this occasion, by setting the cycle of the auxiliary voltage near the oscillation cycle of interest ion species in the axial direction, the interest ion species are synchronized with the auxiliary electric field to be certainly unstabilized in the detector side.

摘要： An ion trap/time-of-flight mass spectrometer, which can perform accurate mass measurement of a product ion based on MS/MS and MSn has an ion source for ionizing a sample, an ion trap capable of temporarily trapping ions, and a time-of-flight mass spectrometer. The ion source produces ions of the sample as a measurement target and ions of a reference sample each having a known mass value. A precursor ion is selected from among the ions of the measurement target sample, and the selected precursor ion is excited and fragmented in the ion trap to produce a product ion. The reference sample ions are introduced to and trapped in the ion trap. The trapped product ion and reference sample ions are expelled out of the ion trap and introduced to the time-of-flight mass spectrometer, thereby obtaining a mass spectrum.
