    Abstract: 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.

    Abstract: To prevent lowering of sensitivity of a flow cell based on total reflection of light at an outer face of a glass capillary at a joint part with a pipe, the flow cell includes, at joint parts with a pipe 605 to introduce solution to a glass capillary 601 and with a pipe to discharge solution from the capillary, an inorganic material layer 602 that reflects measurement light to modify the outer face of the glass capillary as well as a reinforcement layer 711 to modify the surface thereof.

    Abstract: 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.
