摘要： A recess into which a protrusion of a plunger seal is to be fitted is provided at a part of a pump head where a plunger is to be inserted into a pump chamber. The plunger seal seals the pump chamber by an outer circumferential surface of the protrusion coming into close contact with an inner circumferential surface of the recess and a surface of a flange on the side of the protrusion coming into close contact with a circumferential edge surface of the recess of the pump head due to the protrusion being fitted into the recess and being pressed by a backup ring toward the pump chamber. The inner circumferential surface of the recess of the pump head and the circumferential edge surface of the recess are covered by a film of an acid-resistant material.

摘要： An analyzer control system 20 for monitoring and controlling an analyzer 20 includes: a plurality of sensors for detecting the condition of each component of the analyzer; a potential problem inference section 23 for receiving detection results obtained with all or part of the sensors and for inferring whether or not the analyzer is in a potentially problematic condition; and a potential problem display section 32 for showing, on a display screen, information on the potentially problematic condition. The “potentially problematic condition” is neither a condition in which the analysis data being collected by the analyzer are unusable, nor a condition which requires deactivation of the analyzer; it is a condition in which the analyzing operation may be continued for the time being, although the analyzer is likely to soon fall into the aforementioned situations if the operation is further continued. The already collected data can be properly used.

摘要： A base and a stator forming a housing are joined by a stator position adjustment member. The adjustment member is a ring-shaped member having an inner diameter that is equal to the outer forms of the base and the stator, and threads opposite to each other are provided to an upper portion and a lower portion of the inner circumferential surface, along the circumferential direction. A thread for being screwed with the thread is provided, in the circumferential direction, to each of an upper portion of an outer circumferential surface of the base and a lower portion of an outer circumferential surface of an outer wall member of the stator. When the adjustment member is rotated, the base and the stator move in the direction of separating from each other or in the direction of coming close to each other.

摘要： A solvent delivery device comprises a solvent delivery pump and a flow path switching valve. The flow path switching valve is connected to downstream ends of mobile phase sending flow paths and the solvent delivery pump is to be connected to one of the mobile phase sending flow paths by switching the flow path switching valve. At least one of the mobile phase sending flow paths includes a buffer solution sending flow path, and the buffer solution sending flow path includes a buffer solution storage section, a cleaning solution storage section, and a mobile phase switching valve for switching connection of the flow path switching valve to one of the storage sections.
