摘要： A bioinert piping (1) that has a flow path (2) provided inside and a main body portion (10) between end portions (8, 8) includes a resin tube (4) that forms an inner wall of the flow path (2) over an entire length of the flow path (2), and a metal tube (6) that accommodates the resin tube (4) inside so as to cover the outer peripheral surface of the resin tube (4) over at least an entire length of the main body portion (10). The metal tube (6) is plastically deformed toward an inner side so that the outer peripheral surface of the resin tube (4) and an inner peripheral surface of the metal tube (6) are in liquid-tight contact with each other.

摘要： A field-flow fractionation device includes a separation channel, a carrier fluid supplier, a separation membrane, a waste liquid chamber, a cross-flow flow rate adjuster, and a carrier fluid adder. The carrier fluid adder is configured to add, to a flow of a carrier fluid having passed through the separation membrane, a flow of another carrier fluid at a carrier fluid adding position set on an upstream side of the cross-flow flow rate adjuster so that the flow rate of the carrier fluid flowing into the cross-flow flow rate adjuster is larger than the flow rate of the carrier fluid having passed through the separation membrane.

摘要： A resin tube is prepared. Further, a formation tool having a pressing surface and a projection that projects from the pressing surface and is insertable into the resin tube is prepared. The projection of the formation tool is inserted from an end of the resin tube into the resin tube. The pressing surface of the formation tool is pressed against an end surface of the resin tube. Thermal energy is applied to the end of the resin tube, whereby a shape of the pressing surface of the formation tool is transferred to the end surface of the resin tube, and the end of the resin tube is formed into a flange shape.

摘要： Even though a pump head part is finally fixed to a pump body with a fixing member, the pump head part is movable relative to the pump body perpendicular to the axial direction of a plunger at a stage before the pump head part is fixed with the fixing member. In this state, if a plunger driving part is moved to a predetermined location on the front end side of the pump body and the pump head part and the plunger driving part are fitted to each other, the pump head part is positioned where the center axis of the plunger and the center axis of the pump chamber are substantially aligned. By fixing the pump head part to the pump body with the fixing member at this location, it is possible to assemble a plunger pump with the center axis of the plunger and the center axis substantially aligned.

摘要： The present invention relates to a particle manipulation method to disperse magnetic particles 70 in a liquid 35 filling up a tube container 10, wherein a circumferential direction moving step to move the magnetic particles 70 along the circumferential direction of the container 10 in the liquid 35 and in a radial direction moving step to move the magnetic particles 70 as crossing the radial direction of the container 10 in the liquid 35 are implemented repeatedly. Such manipulations can be achieved by combining rotation of the container and gravity force and magnetic field manipulations.

摘要： A binary pump in which an operation controller causes each of two liquid delivery pumps to execute, while a secondary discharge process is executed, a suction process, a first pre-pressurizing process, and a standby process. The operation controller causes each of the two liquid delivery pumps to execute a second pre-pressurizing process before proceeding from the secondary discharge process to the primary discharge process. Furthermore, the operation controller causes, as long as continuous liquid delivery by each of the two liquid delivery pumps is not interrupted, at least one of the two liquid delivery pumps to execute avoidance operation of interrupting the standby process and proceeding to the second pre-pressurizing process by using the operation state of each of the two liquid delivery pumps, so as to avoid overlap of execution time zones of the primary discharge processes of the two liquid delivery pumps.

摘要： A liquid feeding device includes a discharge channel, a pump part, a feeding pressure sensor, a non-discharge pressure sensor, a pre-compression part, and a pre-compression speed determination part. The pump part has plunger pumps connected in series or parallel. At least one of the plunger pumps is a closed pump in which communication with the discharge channel is disconnected during a non-discharge time. The pre-compression part causes the closed pump that is after the suction process for sucking the liquid into a pump chamber is completed and during the non-discharge time to execute a pre-compression process to perform a discharge operation until a non-discharge pressure is substantially the same as a feeding pressure based on output of the feeding pressure sensor and output of the non-discharge pressure sensor. The pre-compression speed determination part determines a pre-compression speed of the closed pump in the pre-compression process.

摘要： The liquid feeding device includes a discharge speed calculation part configured to calculate a discharge speed v of the plunger pump so that a converted value LATM under an atmospheric pressure of a flow rate LPRE of the mobile phase discharged to the discharge channel from the pump part becomes a set flow rate LSET using a volume V of the mobile phase in the pump chamber of the closing pump immediately before the precompression process is started, a volume ΔV reduced due to the precompression process of the mobile phase in the pump chamber of the closing pump, and a feeding pressure P; and a discharge operation controller configured to control a discharge speed of the plunger pump to a discharge speed v calculated by the discharge speed calculation part.
