Abstract
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.
