Abstract
An analysis apparatus column oven equipped with a plurality of columns is capable of efficiently performing heat conduction on column basis, recognizing a column cartridge that holds a column, and being easily exchanged on column basis. The column change mechanism includes a ferrule, a movable ferrule connector, a pipe, a fastener pull, a fastener fitting, a column cartridge presser, a slide guide, an RFID reader, a fixed wall, a column changer heat insulating member, a fixed bottom plate, a receiver, and a fixed fitting. A plurality of column cartridges can be installed in the heat block, and are in contact with the column heat block to control the temperature in the column cartridges. The column cartridge is fixed between left and right column change mechanisms, and when the fixed column cartridge is opened, the column change mechanism on the left side is moved leftward and opened.
