    Abstract: A method of fabricating miniature quadrupole electrostatic mass filter has been previously described. The electrodes are metallised cylinders, mounted in grooves etched in oxidised silicon substrates, which are held apart at the correct spacing by cylindrical spacer rods. This invention concerns an ion source mounted on extensions of the spacer rods, which project beyond the mass filter. The ion source consists of a cold-cathode electron emitter, which emits electrons with energies sufficient to cause impact ionisation, and electrostatic optics suitable for coupling the ion flux into the mass filter. Methods of constructing a single self-aligned electron source and a similar dual source are described. Arrangements for mounting the electron source and the ion coupling lens so that the electron and ion beams travel at right angles to one another for efficient separation are described. A method of fabricating a self-aligned one-dimensional einzel electrostatic lens from metallised cylinders mounted in the silicon substrates using etched grooves is described. A method of fabricating a-self-aligned two-dimensional einzel lens from metal plates is also described.

    Abstract:  ガスに含まれる複数の分子成分を互いに同時にPI法によるイオン化対象とする。例えば、ある瞬間に発生したガスに含まれる複数の分子成分をPI法に基づいてリアルタイムで正確に分析する。  試料室R0内の試料Sで発生したガスを分析室R1へ搬送するガス搬送装置4と、ガスをイオン化するイオン化装置19と、イオンを質量電荷比ごとに分離する四重極フィルタ21と、分離されたイオンを検出するイオン検出装置22とを有するガス分析装置である。イオン化装置19は、ガス搬送装置4のガス排出口の近傍に設けられたイオン化領域と、そのイオン化領域へ光を照射するランプ33Aとを有する。ランプ33Aは、光の指向性がレーザ光よりも低くて広がって進む光を放射するので、イオン化装置19内のイオン化領域へ入ったガスは広い範囲で光の照射を受け、その内部の複数のガス成分が同時にイオン化される。

    Abstract: A quadrupole is filled with ions and the ions are cooled by applying a pressure and gas flow within the quadrupole. Ions are trapped in the quadrupole by applying a DC voltage and an RF voltage to quadrupole rods of the quadrupole, one or more DC voltages to a plurality of auxiliary electrodes of the quadrupole, and a DC voltage and an RF voltage to an exit lens at the end of the quadrupole. The ions are coherently oscillated after the filling and cooling by applying a coherent excitation between at least two rods of the quadrupole rods. The coherently oscillating ions are axially ejected through the exit lens and to a destructive detector for detection by changing one or more voltages of the one or more DC voltages of the plurality of auxiliary electrodes and changing the DC voltage of the exit lens.

    Abstract: Mass analysers and methods of ion detection for a mass analyser are provided. An electrostatic field generator provides an electrostatic field causing ion packets to oscillate along a direction. A pulse transient signal is detected over a time duration that is significantly shorter than a period of the ion oscillation or using pulse detection electrodes having a width that is significantly smaller than a span of ion harmonic motion. A harmonic transient signal is also detected. Ion intensity with respect to mass-to-charge ratio is then identified based on the pulse transient signal and the harmonic transient signal.
