摘要： An ion beam having a good converging property and a good quality is provided by satisfying the limitations controlling both angle of dispersion and the width of beam at the same time. The voltage 12d of a repeller electrode 1f in an ion source of electron bombardment type is input to an ion source state monitor 11 and the ion source state monitor 11 output a predicted value 12e of the voltage applied to an extractor electrode 1g to an extractor power source 9. As for the extractor electrode system, the width of a slit in the acceleration electrode 1b is made larger than the width of a slit of the extractor electrode 1g, and the extractor electrode 1g is set in a position apart from the acceleration electrode 1b by the distance nearly equal to the distance between the acceleration electrode 1b and the ion generating region 2a. By doing so, the electric field leaked from the slit of the acceleration electrode 1b to the inside of the ionization chamber 1a expands to the vicinity of the ion generating region. As the result, the ion beam 2 is effectively extracted to pass through the slits in the acceleration electrode 1b and the extractor 1g. The amount of the current passing through the slits is measured with an ion current monitor 8a and the voltage 12f of a converging electrode 1d is adjusted so that the value of the current becomes the maximum.

A mass spectrometer comprises: an ionization section for ionizing a sample at substantially atmospheric pressure; a first and a second intermediate pressure section in which the pressure is maintained lower than the pressure in said ionization section; a high vacuum section in which the pressure is maintained lower than the pressure in said intermediate pressure section and in which a mass spectrometric means for subjecting ions to mass spectrometry is disposed; a first pore electrode disposed between said ionization section and said first intermediate pressure section; an intermediate pore electrode disposed between said first intermediate pressure section and said second intermediate pressure section; and a second pore electrode disposed between said second intermediate pressure section and said high vacuum section. A first converging electrode is provided in the first intermediate pressure section, the first converging electrode having an opening towards the first pore electrode and another opening towards the intermediate pore electrode. The opening towards the first pore electrode has a larger diameter than the opening towards the intermediate pore electrode, such that the first converging electrode has a tapered shape.

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.

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.
