Conventionally, in liquid chromatography, particularly high-performance liquid chromatography, a high-pressure pump has often been used as a means for feeding a carrier liquid into a separation column. As such a high-pressure pump, for example, a syringe type pump has been commercially available. This device has the disadvantage that when replacing the carrier liquid, cleaning must be repeated several times to remove the carrier liquid remaining in the cylinder. As other types of high-H pumps, various types of reciprocating plunger force type pumps are commercially available. These things produce a pulsating flow in synchronization with the reciprocation of the plunger.
Not only can noise be generated when detecting extremely ill sample components that are developed and separated using a separation column, but the expensive separation column may be damaged, and the inside of the cylinder must be kept airtight from the outside air. The members necessary for high-pressure sealing so that the plunger can reciprocate in a state where the plunger is reciprocated wear out as the plunger reciprocates, often resulting in liquid leakage.

A cartridge type pump has been proposed as a new pump to solve these problems (Japanese Patent Application No. 56-2
03434 and Japanese Patent Application No. 5620'9859 θ Drinking Music) 3. In a cartridge-type pump, the cartridge is made of a material such as a polymer and left behind by injection molding, etc., and is used to be disposable. Although convenient and preferable, it is not always easy to perform injection molding using a polymer or the like in order to manufacture an elongated cartridge, especially one with a constant inner diameter.

In other words, the cartridge of the present invention is a cartridge for containing a carrier liquid used in liquid chromatography, and is made of a material capable of stress deformation in which at least one of the inner diameter and outer diameter is slightly changed in the axial direction. It consists of a circular cylinder made of steel and a piston that can reciprocate within the cylinder, and has a discharge port for the carrier liquid, and the four chambers formed by the cylinder and the piston accommodate the carrier liquid. This is a cartridge that is housed in a rigid case and that discharges carrier liquid when an external force is applied to the piston.

As a case for the rigid body, a case 8 made of stainless steel is used, and the inner diameter is d = 25. It is Ormn. When the constant speed rotation motor J4 is driven, the slide shaft 16 is sent out with a constant movement, and the piston 3 is moved forward toward the tip of the cylinder 2. At this point, the carrier liquid 5 in the cartridge is sent to the separation column 11, but an internal pressure p is generated in the cartridge depending on the resistance of the separation column 11 and the liquid sending rate q. According to the experimental results, q=11 mixture/
The height of the shaft is 40 kg/d, and as a result, the cylindrical portion of the cylinder 20 experiences a circumferential stress σt of 180 kg/d. In response to the expansion 1, the outer circumference of the cylindrical portion of the cylinder 2 is pressed against the inner wall of the stainless steel case 8, and at the same time, the inner diameter of the cylinder 2 of the cartridge increases, creating a cylinder inner chamber with an inner diameter that is approximately constant as the axial force rotates. begins to form. Therefore, simply by keeping the feed amount of the piston 3 constant, the carrier liquid feeding speed also becomes constant, and a fixed amount of liquid feeding without pulsation can be realized. In addition, when the -th measurement is completed, the used cartridge is replaced with a new one filled with carrier liquid.
It is possible to immediately start the next measurement just by changing the I/IC.
