Patent number: 8683879Abstract: A sample injecting device is provided for reducing carryover. The sample injecting device includes the following mode: a needle is set at a low descending speed when sample is injected into an injection port in a total-volume injection manner by the sample injecting device. When the needle is in contact with the injection port, the needle is set at a low speed, thereby increasing the accuracy of the position of the needle relative to an injection hole and decreasing friction between the needle and the injection hole. Contaminants present in the injection hole are prevented from easily flowing from the injection hole into an analyzing flow path, so as to achieve an excellent low carryover.Type: GrantFiled: February 17, 2011Date of Patent: April 1, 2014Assignee: Shimadzu CorporationInventor: Masami Tomita

Patent number: 8322374Abstract: A channel switching valve is disclosed. The channel switching valve has a stator and a body section each having a connecting surface. The stator and the body section are removably fixed to each other by bolts at their connecting surfaces. Each of the connecting surfaces has a protruding/recessed pattern formed thereon, and the patterns are designed to fit into each other. By rotating the stator and the body section relative to each other, the stroke of a spring is changed between a position where the protruding/recessed patterns of the stator and the body section are fitted into each other and a position where they are not fitted into each other. The spring is held in the body section in its compressed state to urge the rotor toward the stator. An urging force for pressing the rotor against the stator is adjusted by changing the stroke of the spring.Type: GrantFiled: December 17, 2008Date of Patent: December 4, 2012Assignee: Shimadzu CorporationInventor: Masami Tomita
