摘要： A sample introduction method for reducing carry-over is provided. After a sample introduction device in a total volume injection method draws a proper amount of a sample solution from a sample container and further draws a solution with the same composition as a mobile phase solution with a needle 24, the needle 24 is inserted into an injection port 25. When flow paths are switched to communicate a liquid feeder, a sample loop 23, the needle 24, the injection port 25, and a separation/detection section, the solution with the same composition as the mobile phase solution is forced into a gap between the injection port 25 and the needle 24. Therefore, the samples squeezed out of a tip section of the needle 24 during the switching of the flow paths are prevented from being forced into the gap between the needle 24 and the injection port 25.

摘要： A sample introduction device for reducing carry-over is provided. In the sample introduction device, when a high pressure valve 51 is switched from a load status to an injection status in a total volume injection method, the communication between a stator hole d in communication with an injection port 25 and a stator hole c connected to a flow path toward a separation/detection section 30 occurs earlier than the communication between a stator hole b in communication with a liquid feeder 10 and a stator hole a in communication with a needle 54. A length of a rotor groove Y communicating stator holes d and e or stator holes d and c is set longer than a length of another rotor groove X.

摘要： A sample injection port 10 for injecting a sample into a chromatograph or other devices is composed of a body 13 made of an inelastic material, a first seal member 14 made of an elastic material and attached to one end of the body part 13, and a second seal member 15 made of an elastic material and attached to the other end of the body part 13. A first through hole formed in the first seal member 14 , a second through hole formed in the second seal member 15 and a third through hole formed in the body part 13 are coaxially connected to form an introduction hole for sample injection. With this construction, a sample injection port which has a small inner diameter, is easy to manufacture, and yet capable of achieving a high pressure resistance can be provided.

摘要： An autosampler is provided with a needle, a measuring pump which sucks and discharges liquid through the needle, a movement mechanism for the needle, and an injection port which has a needle sealing surface. A sample liquid is sucked into the needle and then the sample liquid discharged with the tip of the needle pressed to the needle sealing surface. When cleaning the needle sealing surface, a cleaning liquid in within the injection port is sucked and then the cleaning liquid is discharged and sucked into the injection port at a position at which the tip of the needle does not make contact with the needle sealing surface. Alternatively, after the cleaning liquid is discharged into the injection port, the needle may be caused to perform an up and down motion such that the tip of the needle contacts the needle sealing surface and then is lifted.

摘要： In injecting a sample sucked into a sample loop in an autosampler from an injection needle into an analytical flow path via an injection port by a mobile phase, a sending flow rate of the mobile phase is reduced from a certain flow rate determined in an analysis condition to reduce pressure applied on a joint section between the needle and the injection port to thereby reduce the sample remaining in the injection port.

摘要： It is to provide a quality improving agent for cooked rice which effectively imparts improving effect on loosening properties, anti-aging property, and/or water retentivity to cooked rice with as little influence as possible on the original texture and taste of the cooked rice, a method for producing cooked rice using the quality improving agent, and cooked rice improved in loosening properties, anti-aging property, and/or water retentivity using the method for producing cooked rice. In the process of rice cooking for preparing cooked rice, substituted modified starch whose viscosity has been adjusted to a viscosity range involving a viscosity of 15 mPa·s or higher at 30% by mass in an aqueous solution and a viscosity of 3000 mPa·s or lower at 10% by mass in an aqueous solution by the hydrolysis or molecular weight reduction of the substituted modified starch is added as the quality improving agent for cooked rice. As a result, improving effect on loosening properties, anti-aging property, and/or water retentivity is imparted to cooked rice, while cooked rice having the original texture and taste of cooked rice is produced. Examples of the degradation product of substituted modified starch include degradation products obtained using, as a base material, substituted modified starch(s) of hydroxypropyl starch, hydroxypropylated distarch phosphate, and starch sodium octenylsuccinate.
