    摘要: There is provided a tandem mass spectrometry that, in a quadrupole ion trap, allows small mass-number product ions to be detected without lowering the sensitivity and the resolution. In the quadrupole ion trap, ions are produced by an ion source. Next, the ions are accumulated within a 3-dimensional quadrupole electric field formed by a pair of endcap electrodes and a ring electrode. Finally, the accumulated ions are isolated and dissociated, then being detected. In this quadrupole ion trap, there are provided a mechanism for introducing a laser light, and a mechanism for generating a supplemental alternating-current electric field at the time of the ion dissociation. Moreover, the direction of the supplemental alternating-current electric field and the introduction direction of the laser light are made identical to each other.

    摘要: The quantitative accuracy of analysis is improved without reducing the dynamic range for measurement of concentrations by performing stable ionization through electrospray or the like which repeats sampling and ionization using a movable probe electrode.A voltage is applied from a high-voltage power source 4 to a sample transport electrode 7 having a plurality of probe electrodes 1 and a driving section 3 drives the sample transport electrode 7 to rotate. The plurality of probe electrodes 1, to which a sample solution 5 is adhered, are sequentially transported to an inlet 21 of a mass spectrometer 20, thus electrospray ionization is continuously performed.
