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.

Liquid mixing device, and liquid chromatography apparatus

A pipe connection joint which is repeatedly usable when an analysis column 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.

An apparatus capable of improving image quality by making it possible to suck specimens of different sizes electrostatically, and uniformalizing an electric field of a specimen edge portion, while suppressing increase in prime cost is provided. Specimen holding means is an electrostatic chuck, a master flat plane part surrounding a specimen of the largest size of specimen sizes, and an opening surrounding a specimen size except for the largest specimen size are included at an outer peripheral portion of the electrostatic chuck, a dummy specimen attachable to and detachable from the electrostatic chuck is included, and at a time of switching the specimen size, a dummy specimen is selected (or may be prevented from being used).
