Separation column connection device, connection method, and analysis system

An analysis system comprising:

• a separation column connecting device which includes:
• a column holder for retaining a separation column;
• a first fitting holder carrying a first fitting which includes a seal portion to be connected to an upstream seal portion of the separation column and is connected with an upstream pipe;
• a second fitting holder carrying a second fitting which includes a seal portion to be connected to a downstream seal portion of the separation column and is connected with a downstream pipe;
• a body member to which either one of the first fitting holder and the second fitting holder is fixed;
• a driver for moving, relative to the body member, the first fitting holder or the second fitting holder that is not fixed to the body member and moving the column holder relative to the body member;
• a guide for guiding the column holder in a direction of movement driven by the driver;
• and
• an elastic body disposed between the column holder and the second fitting holder;
• a pump for feeding a sample to the separation column via the upstream pipe;
• a sample injection part for injecting the sample into the upstream pipe;
• a detector for detecting an elution component from the separation column;
• and
• a data processor for analysis of detection result obtained by the detector.

A separation column connection method comprising:

• placing a separation column between a first fitting and a second fitting, the first fitting including a seal portion to be connected to an upstream seal portion of the separation column and is connected with an upstream pipe, and the second fitting including a seal portion to be connected to a downstream seal portion of the separation column and is connected with a downstream pipe;
• first connecting the first fitting to the separation column by bringing the first fitting and the second fitting close to each other by applying a repulsive force or a resistive force between the separation column and the second fitting;
• and
• connecting the second fitting to the separation column by further bringing the first fitting and the second fitting closer to each other.
