Abstract: For providing a column oven and chromatography capable of reliably preventing misconnection of a storage unit to a connecting part, the column oven includes: a hollow casing; a column unit including an analysis column, which is arranged in the casing and allows a mobile phase (Q) to flow through, and a storage unit, which is attached to the analysis column and stores data of the analysis column; multiple holding parts, which are arranged in the casing and hold the analysis column; a tabular fixing plate, which is arranged in the casing and fixes the respective holding parts to the casing; multiple connecting parts, which are arranged in the casing and connect the storage unit electrically and detachably; and a heating part, which heats the analysis column held by the holding parts in the casing.

Abstract: To diminish complication and difficulty in attachment and detachment of analytical columns to and from a column oven. The column oven includes, in a column housing part that includes a space for housing the plurality of analytical columns, a column rack that holds the plurality of analytical columns, an inlet switching valve, and an outlet connection portion. At least either the inlet switching valve or the outlet connection portion is formed integrally with the column rack and capable of being attached to and detached from the column housing part together with the column rack.
