    • A mass spectrometer that employs ion velocity mapping. The mass spectrometer includes velocity mapping ion optics that focus the ions based on their velocity. The focused ions are then directed into a deflection region between two deflection plates. A pulse is applied to the deflection plates that deflect the ions in a transverse direction also according to their mass. The pulse is turned on before the first ion in an ion packet reaches the deflection region, and is turned off before the first ion exits the deflection region. The focused and deflected ions are then reflected by a reflecting device that directs the ions along separate paths to a detector. The detector provides an image of the ion paths, where the location of a spot on the image represents ions of a certain mass and the size of the spot indicates the various velocities of the ions of that mass.
    • 使用离子速度映射的质谱仪。 质谱仪包括速度映射离子光学,其基于它们的速度聚焦离子。 然后将聚焦离子导入两个偏转板之间的偏转区域。 一个脉冲被施加到偏转板上,它们也根据它们的质量沿横向偏转离子。 在离子包中的第一离子到达偏转区域之前,脉冲被打开,并且在第一离子离开偏转区域之前被关闭。 聚焦和偏转的离子然后被反射装置反射,反射装置将离子沿着分离的路径引导到检测器。 检测器提供离子路径的图像,其中图像上的点的位置表示一定质量的离子,斑点的大小表示该质量的离子的各种速度。

    • The present invention relates to a method for preparing a tricyclic derivative, and more particularly, to a method for preparing a tricyclic derivative intermediate with high yield and purity, the method including: introducing a hydroxy group by esterifying and substituting 2-fluoroisophthalic acid compound; introducing a piperidyl group; introducing a hydroxy group through reduction reaction; and then hydrolyzing the resultant compound, and to a method for preparing the tricyclic derivative using said intermediate. According to the method of the present invention, it is possible to provide a tricyclic derivative and an intermediate thereof with high productivity and economic feasibility as well as high purity and yield, by purifying a compound using re-crystallization unlike typical methods of using column chromatography. In addition, the method of the present invention can be usefully used for industrial mass production because sodium borohydride or lithium aluminum hydride with low risk of a fire is used unlike typical methods of using lithium borohydride which is not industrially applicable due to high risk of a fire.
    • 本发明涉及一种制备三环衍生物的方法,更具体地说涉及一种制备高产率和纯度的三环衍生物中间体的方法,其包括:通过酯化和取代2-氟间苯二甲酸化合物引入羟基; 引入哌啶基; 通过还原反应引入羟基; 然后水解所得化合物,以及使用所述中间体制备三环衍生物的方法。 根据本发明的方法,通过使用重结晶纯化化合物,可以提供具有高生产率和经济可行性以及高纯度和收率的三环衍生物及其中间体,与使用柱色谱法的典型方法不同 。 此外,本发明的方法可以有用地用于工业大规模生产,因为使用低风险的硼氢化钠或氢化铝锂不同于使用不具有工业上适用的硼氢化锂的典型方法,这是因为高风险的 火。
