    Abstract: A differential pumping system in which a vacuum chamber is manufactured to have a plurality of vacuum pumps and conductance limit plates between the vacuum pumps. The dif¬ ferential pumping system in which an ion is implanted from an ionization source, passes through the vacuum chamber and is detected by a detection unit includes a plurality of vacuum pumps in the vacuum chamber and one or more conductance limit plates between the vacuum pumps, and the conductance limit plates form an angle less than 90° with the transmission direction of the ion. According to such a constitution, higher degree of vacuum and the ion transmission efficiency are maintained without increasing the length of the vacuum chamber. Furthermore, it is possible to minimize the attenuation of an ion detection signal due to a collision with a neighboring neutral molecule, improving the sensitivity of an ion detection device.

    Abstract: An apparatus for signal improvement of Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer. The apparatus includes trapping electrodes that are disposed to be spaced from each other and face each other; excitation and detection electrodes that are disposed between the trapping electrodes and are aligned at a predetermined angle with the trapping electrodes so as to form a trap; first control electrodes that are connected to the excitation and detection electrodes through capacitors and are electrically independent of the other electrodes; and second control electrodes that are disposed on the trapping electrodes and are electrically in¬ dependent of the other electrodes.

    Abstract: The present invention relates to an ion trap mass spectrometer using a cold electron source, in a production of a portable mass spectrometer, in which a microchannel plate (MCP) module is used, initial electrons are induced by injecting ultraviolet photons emitted from an ultraviolet diode to a front surface of the MCP module, electron beams amplified from the electrons are amplified using a channeltron electron multiplier (CEM), the amplified electron beams are accurately adjusted and injected into an ion trap, thus increasing the amplification rate, and since a quadrupole field is used as an ion filter which returns the initially injected electrons to the inside of an ion trap mass separator, the ionization rate increases.
