    Abstract: 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. As a result, a local load acting on the rotor during a high-pressure liquid-feeding process is reduced, so that the contact surface is prevented from being scraped off by the edge of the opening of a port during the rotation of the rotor.

    Abstract: A method of liquid chromatography includes providing an injection valve, drawing a sample and a diluent while mixing, pushing the mixed sample and diluent onto a sample loop of the injection valve, and injecting the mixed sample and diluent. An analytical apparatus includes a proportioning unit, an injection valve having a sample loop, and a sample pump. The injection valve has a draw state and a load state, and has a port in fluidic communication with an outlet port of the proportioning unit. The sample pump is in fluidic communication with the outlet port of the proportioning unit, if the injection valve is in the draw state, to draw both a sample and a diluent through the proportioning unit and the injection valve, and in fluidic communication with the sample loop, if the injection valve is in the load state, to push the drawn sample and diluent onto the sample loop.

    Abstract: In a preferred embodiment, a channel switching valve has a stator having a connecting surface and a body section having a connecting surface, and 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 protruding/recessed patterns are designed to be fitted 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 stator and the body section are fixed to each other in a state where their protruding/recessed patterns are fitted into each other and a position where the stator and the body section are fixed to each other in a state where their protruding/recessed patterns 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.

    Abstract: The present invention relates to a microfluidic device for separating the components of a fluid sample. A cover plate is arranged over the first surface of a substrate, which, in combination with a microchannel formed in the first surface, defines a separation conduit for separating the components of the fluid sample. An inlet port in fluid communication with the separation conduit allows a mobile phase containing a gradient of a selected mobile-phase component to be introduced from an integrated gradient-generation means to the separation conduit. A method is also provided for separating the components of a fluid sample using a mobile phase containing a gradient of a selected mobile-phase component, wherein the gradient is generated within a small volume of mobile phase.
