Chromatograph

A chromatograph comprising:

• a separation column that incorporates a stationary phase;
• a column cartridge that accommodates the separation column and is detachably provided in a predetermined column installation position;
• an upstream pipe that is detachably provided on the column cartridge in a state of being installed at the column installation position, and configured to supply a mobile phase to the separation column of the column cartridge;
• a downstream pipe that is detachably provided on the column cartridge in a state of being installed at the column installation position, and configured to deliver the mobile phase that has passed through the separation column of the column cartridge;
• and
• a cover that integrally covers the column installation position, the upstream pipe, and the downstream pipe to separate an inner side and an outer side of the cover from each other, wherein
• the cover has an insertion hole that penetrates the cover and allows the column cartridge to be installed from the outer side of the cover to the column installation position.
