Abstract: Provided are: a flow path switching valve that reduces the pressure load in a contact surface outer peripheral section of the flow path switching valve and inhibits friction between constituent components; and a liquid chromatographic device using the flow path switching valve. The flow path switching valve is provided with a stator having a plurality of through holes and a seal having conduction grooves for causing the through holes to conduct. The seal has a first portion present vertically beneath a region comprising at least a surface of contact with the stator, and a second portion having lower rigidity than the first portion, on the outside of the first portion. Due to this configuration, it is possible to reduce the pressure load when a flow path of a liquid is switched under high-pressure conditions, and inhibit the phenomenon of friction itself.

Abstract: A composite structure with high pressure resistance that is suitable for a flow channel is produced by reducing the number of components while maintaining the excellent chemical resistance and high stress tolerance inherent to a glass substrate and a resin substrate. A glass substrate surface is modified with a hydrolyzable silicon compound, and the glass substrate is brought into contact with the resin substrate. Subsequently, the contact surface between the glass substrate and the resin substrate is heated to a temperature from the glass transition temperature to the pyrolysis temperature of the resin substrate, eliminating gaps between the glass substrate and the resin substrate to bring them into close contact with each other, and causing chemical binding or anchor effects between the glass substrate and the resin substrate via the hydrolyzable silicon compound. Thus, the glass substrate and the resin substrate are firmly fixed to each other.

Abstract: A detector for liquid chromatography has light sources that generate light in an ultraviolet region and in a near-infrared region; a flow cell, through which sample liquid flows; an optical system to let light generated from the light sources become incident on the flow cell concurrently; a detection element that detects light in the ultraviolet region that passes through the flow cell; a detection element that detects light in the near-infrared region that passes through the flow cell; and an arithmetic operation part that performs arithmetic operation of a first signal value obtained from the detection element and of a second signal value obtained from the detection element. The arithmetic operation part combines the first signal value and the second signal value to calculate a signal value with a reduced baseline fluctuation resulting from a mobile phase during a gradient analysis.
