    摘要： A liquid-mixing device that minimizes solvent leakage and reduces creep of or damage to the component parts of said liquid-mixing device even at ultrahigh pressures of 100 MPa and up. Also, a liquid chromatography device using said liquid-mixing device. Said liquid chromatography device is provided with a supply pump that supplies a plurality of different solutions, a liquid-mixing device that mixes the supplied solutions, a sample injection device that injects a sample into the mixture of solutions, a column that separates the components of the injected sample, and a detector that detects the separated components. The liquid-mixing device has an inlet-side connector through which the plurality of different solutions flow in, a liquid-mixing section in which said solutions are mixed, and an outflow-side connector through which the mixed solutions flow out. The inlet-side connector and the liquid-mixing section are directly bonded to each other via diffusion bonding, as are the liquid-mixing section and the exit-side connector.

    摘要： The present invention provides a pipe connection joint which is repeatedly usable when an analysis column or the like is replaced with another in a liquid chromatographic device. To this end, an elastic body is built into a compression screw for inserting a pipe passed through a ferrule into the analysis column to thereby axially movably support the pipe, and a pipe clamp is secured in advance at a predetermined position of the pipe. A distance between the ferrule and the pipe clamp changes on the basis of the length of a portion of the pipe sticking out from the ferrule and the pressing force of the elastic body applied to the pipe. Consequently, in a liquid chromatographic device, a pipe connection joint for the analysis column or the like can be repeatedly used of plural times.
