Definitions

  • Carrier gas is supplied to the ionization chamber 31 together with each sample component from the gas chromatograph unit 2.
  • Each sample component is ionized in the ionization chamber 31.
  • Examples of the ionization method include EI (Electron Ionization), PCI (Positive Chemical Ionization), NCI (Negative Chemical Ionization), and the like. Not limited.
  • the mass spectrometer 3 is provided with a door 4 for opening and closing the vacuum chamber 30.
  • the door 4 is attached to a part of the wall surface 301 for partitioning the ionization chamber 31 in the housing 300 so as to be openable and closable.
  • the door 4 may be provided on the wall surface that partitions the vacuum chamber 30 other than the ionization chamber 31, such as the first vacuum chamber 32 or the second vacuum chamber 33.
  • the wall surface 301 of the housing 300 is formed with an opening 302 for an operator to insert a hand or a tool during maintenance or the like inside the housing 300.
  • the opening 302 is formed in a square shape having a horizontal width and a vertical width of about 10 to 20 cm, respectively, but the opening 302 is not limited to such a shape.
  • the opening 302 communicates with the vacuum chamber 30 and is opened and closed by the door 4.
  • the door 4 is rotatably supported by the hinge portion 5 between the open state in which the opening 302 is open (the state shown in FIG. 2) and the closed state in which the opening 302 is closed by the door 4.
  • the end of the door 4 opposite to the hinge portion 5 side is separated from the opening 302 in the open state and close to the opening 302 in the closed state.
  • the door 4 includes a closing portion 41 and a holding portion 42.
  • the closing portion 41 is a plate-shaped member having a planar shape larger than the opening 302, and closes the opening 302 in the closed state.
  • the closed portion 41 can be formed with a thickness of about 10 to 20 mm by using a material containing, for example, aluminum, but the closed portion 41 is not limited to this.
  • the closed portion 41 is provided with a seal member 43 on the surface (inner surface 411) that is on the vacuum chamber 30 side in the closed state.
  • the seal member 43 is composed of an annular O-ring larger than the opening 302 of the housing 300. When the door 4 is in the closed state, the seal member 43 comes into contact with the peripheral edge of the opening 302 in the housing 300.
  • the closing portion 41 is positioned with respect to the opening 302 by the positioning mechanism 6 described above.
  • the door 4 is rotated from this state to the closed state a little more, as shown in FIG. 3B, before the end portion (first end portion 431) on the hinge portion 5 side of the seal member 43, The end portion (second end portion 432) opposite to the hinge portion 5 side comes into contact with the peripheral edge portion of the opening 302.
  • the first end portion 431 of the seal member 43 is not in contact with the peripheral edge portion of the opening 302, but the door 4 can be rotated to the closed state a little more to compress the second end portion 432 of the seal member 43.
  • the first end portion 431 of the seal member 43 also comes into contact with the peripheral edge portion of the opening 302.
  • the positioning mechanism 6 is not limited to the configuration including the convex portion 61 provided in the housing 300 and the concave portion 62 provided in the closed portion 41.
  • the convex portion 61 may be provided in the closed portion 41 and the concave portion 62 may be provided in the housing 300.
  • the convex portion 61 or the concave portion 62 may be provided in a portion (for example, a holding portion 42) other than the closing portion 41 in the door 4.
  • the structure is not limited to the convex portion 61 and the concave portion 62, and the door 4 may be positioned by using another member such as a magnet.
