    摘要:  周回軌道におけるイオンの追い越しに起因する複雑な周回数の判定などを必要とせず、広い質量範囲に亘る高質量分解能のマススペクトルを自動的に取得する。まず、イオンの追い越しが生じない条件で目的試料の質量分析を行い、低質量分解能のマススペクトルを得る(S1、S2)。そのマススペクトルに現れるピークを所定の条件に基づいて抽出し、抽出したピークに対応する質量範囲を決め、さらにその質量範囲毎にイオンの追い越しが生じない分析条件を決める(S3、S4)。そして、その分析条件に従って、限られた質量のイオンをイオントラップで選択・排出しながら周回飛行させ、高質量分解能のマススペクトルを得る(S5、S6)。最終的に、低質量分解能と高質量分解能のマススペクトルを合成し、広い質量範囲に亘るマススペクトルを作成する(S8)。

    摘要: A radio frequency (RF) drive system and method for driving the ion trap or mass filter of a mass spectrometer has a programmable RF frequency source coupled to a RF gain stage. The RF gain stage is transformer coupled to a tank circuit formed with the ion trap or mass filter. The power of the RF gain stage driving the ion trap or mass filter is measured using a sensing circuit and a power circuit. A feedback value is generated by the power circuit that is used to adjust the RF frequency source. The frequency of the RF frequency source is adjusted until the power of the RF gain stage is at a minimum level.

    摘要: Collision induced dissociation of precursor ions in an ion trap is performed by determining a predicted fragmentation-optimized excitation voltage amplitude based on an indicator of damping gas pressure, such as a damping gas flow rate, and optionally other parameters including precursor ion m/z and an indicator of the Mathieu parameter q . The excitation voltage may then be applied to electrodes of the ion trap in steps of increasing amplitude, wherein at least one of the amplitudes corresponds to the predicted optimum value. Application of the excitation voltage in this manner produces favorable fragmentation efficiencies over a range of operating parameters and for ions of differing chemical properties.
