摘要： A sample injection port 10 for injecting a sample into a chromatograph or other devices is composed of a body 13 made of an inelastic material, a first seal member 14 made of an elastic material and attached to one end of the body part 13, and a second seal member 15 made of an elastic material and attached to the other end of the body part 13. A first through hole formed in the first seal member 14, a second through hole formed in the second seal member 15 and a third through hole formed in the body part 13 are coaxially connected to form an introduction hole for sample injection. With this construction, a sample injection port which has a small inner diameter, is easy to manufacture, and yet capable of achieving a high pressure resistance can be provided.

摘要： A channel-switching valve into which a high-pressure liquid and a low-pressure liquid flow is provided. The channel-switching valve includes a stator and a rotor which has a surface in contact with one surface of the stator and rotates while sliding on the contact surface. The stator has a plurality of liquid flow ports open to the contact surface, and the rotor has a plurality of channel grooves for connecting the liquid flow ports. One of the channel grooves is a straight groove passing through the rotational center of the rotor, and the other channel grooves are line-symmetrically arranged with respect to the straight channel groove. Alternatively, among the channel grooves, the channel grooves into which the high-pressure liquid flows are configured to be located on both sides of the rotational center of the rotor. Thus, a local load acting on the rotor during a high-pressure liquid-feeding process is reduced.

摘要： A sample introduction method for reducing carry-over is provided. After a sample introduction device in a total volume injection method draws a proper amount of a sample solution from a sample container and further draws a solution with the same composition as a mobile phase solution with a needle 24, the needle 24 is inserted into an injection port 25. When flow paths are switched to communicate a liquid feeder, a sample loop 23, the needle 24, the injection port 25, and a separation/detection section, the solution with the same composition as the mobile phase solution is forced into a gap between the injection port 25 and the needle 24. Therefore, the samples squeezed out of a tip section of the needle 24 during the switching of the flow paths are prevented from being forced into the gap between the needle 24 and the injection port 25.

摘要： In order to improve the durability of a rotor, a flow channel switching valve is provided, which includes a stator having a contact plane and a rotor having a contact plane. The stator has circulation openings on the contact plane, and the circulation openings are respectively connected to a plurality of flow channels. The rotor has at least one groove for communicating two of the circulation openings of the stator. The rotor is forced to press against the contact plane of the stator to rotationally slide, so as to switch the circulation openings of the stator that need to be communicated. Polishing is performed on the contact plane of the stator after being applied with a diamond like carbons coating. Furthermore, the contact plane of the rotor is made of a resin.
