摘要： Performing an MS3 with a tandem mass spectrometer causes problems of increase in size of the device and of increase in cost. Likewise, a plural number of times MS/MS analyses are even more difficult. An electrode to create a harmonic potential is disposed in a collision cell, and fragment ions produced by the first-time collision induced dissociation are accumulated in the harmonic potential. Target ions of the subsequent stage are let out, by means of an axial resonance excitation, selectively from the accumulated ions. The ions are excited in the axial direction to have a potential exceeding the harmonic potential. Thereby, the second-time collision induced dissociation is performed by means of a potential difference provided at the subsequent stage. In addition, an operation to return the ions back to the harmonic potential enables a plural number of times MS/MS analyses to be performed.
摘要翻译：使用串联质谱仪进行MS3会导致设备尺寸增加和成本增加的问题。同样，多次MS / MS分析更加困难。用于产生谐波电位的电极设置在碰撞室中，并且由第一次碰撞引起的解离产生的碎片离子累积在谐波电位中。选择性地从累积的离子中排出后续阶段的目标离子，借助于轴向共振激发。离子在轴向上被激发以具有超过谐波电位的电位。因此，通过在后续阶段提供的电位差来执行第二次碰撞诱导解离。此外，使离子返回到谐波电位的操作能够进行多次MS / MS分析。

摘要： An ion resonance condition is corrected accurately in an ion trapping device. Measurements are repeated by alternately applying and not applying a resonance frequency voltage while spectral data is obtained continuously. Data obtained in the absence of the resonance frequency voltage is used as reference data to correct the set data of a resonance condition. As a result, calibration can be made while taking into consideration the variations in the amount of ions that are introduced into the ion trap.

摘要： Recording information is disclosed in which an information recording medium is irradiated with a recording energy beam that is power-modulated into at least a record power level and a record-ready power level lower than the record power level. The information is recorded on the recording medium in the form of length and interval of a mark portion. When forming a mark portion of a predetermined length, the radiation energy of the energy beam is increased as compared with when forming a mark portion of a different length before or after the first pulse of an energy beam pulse train including at least a pulse for forming the mark portion.

摘要： A method for recording information is disclosed in which an information recording medium is irradiated with a recording energy beam power-modulated into at least a record power level and a record-ready power level lower than the record power level. When forming a mark portion of a predetermined length, the radiation energy of the energy beam is increased as compared with when forming a mark portion of a different length before or after the first pulse of an energy beam pulse train including at least a pulse for forming the mark portion. Also, only in the case where the energy beam is modulated by the power lower in power level than the record-ready power level after the last pulse of the energy beam pulse train including at least one pulse for forming a mark portion and the mark portion is followed by a space portion of a predetermined length, the particular radiation energy of low power level is reduced as compared with when the mark portion is followed by a space potion of a different length. The radiation energy is increased and/or decreased.
