Abstract: A member linking mechanism, pairable with a gas chromatograph, which has a small and simple configuration, and is capable of linking two members together with a required fastening force even in a limited space. The member linking mechanism includes a first member having a member linking part with an opening at its distal-end surface; a second member to be linked to the member linking part of the first member; an elastic sealing member sandwiched between the first and second members so as to seal the opening of the distal-end surface of the member linking part; and a linking member for linking the first and second members together via pressure. The linking member includes: a linking member body configured to hold an end part, of the second member, adjacent to the first member; and an elastic deformation part provided to the linking member body.

Abstract: When mounting a second assembly 36 to a first assembly 35 that is fixed to a main body, the second assembly 36 engages a second connection element 54 of a non-rotation unit 361 of the second assembly 36 with a first connection element 354 of the first assembly 35. A rotating part 362 is mounted on the first assembly 35 when the rotation unit 362 is rotated. Therefore, an operator can carry out positioning for the second assembly 36 by connecting the second connection element 54 of the second assembly 36 with the first connection element 354 of the first assembly 35. The second assembly 36 can be smoothly mounted on the first assembly 35 that is fixed to the main body. The second connection element 54 of the non-rotation unit 361 connects with the first connection element 354 of the first assembly 35, so that the non-rotation unit 361 is prevented from rotating together with the rotation unit 362 during use and the assemblies that contact the non-rotation unit 361 are protected from damage.

Abstract: An opening sealing structure is provided with a housing, a step portion, a seal cap, an elastic sealing member, and a cap fixture. The housing has a cap mounting portion having a a cylindrical shape. The step portion is provided on the outer peripheral surface of the cap mounting portion and has a side surface facing the base end side of the cap mounting portion. The side surface of the step portion is inclined along the circumferential direction of the cap mounting portion from the tip end side of the cap mounting portion to the base end side and its inclination angle is smaller on the base end side of the cap mounting portion than on the tip end side. The cap fixture has a cap holding portion movably engaged with the seal cap in a circumferential direction of its outer peripheral surface and an elastic portion connected to the cap holding portion. The elastic portion is provided with a protrusion which engages the side surface of the step portion.

Abstract: A controller includes a temperature prediction unit. The temperature prediction unit predicts, on the assumption that a refrigerant is fed from a refrigerant feeder, an internal temperature of a column oven based on time interval information and decrement information in a memory. Thus, the temperature prediction unit can accurately predict the internal temperature of the column oven when the refrigerant is fed from the refrigerant feeder. If the refrigerant is fed from the refrigerant feeder when the predicted internal temperature of the column oven is suitable for the analysis operation, the internal temperature of the column oven can be brought closer to an appropriate temperature. As a result, the internal temperature of the column oven can be controlled with precision.
