description PURPOSE:To improve cooling efficiency by providing a flow passage to a heating block side provided with a sample evaporating chamber and a detector in a column oven and providing a discharge path which discharges the gas in the oven to the outside. CONSTITUTION:The circumference of a column oven 4 is enclosed to a heat insulating material part S constituted of a heat insulating material. A sample evaporating chamber 1 and a detector 2 are disposed to a heating block 3. A partition plate 16 is provided to face the bottom surface of the upper heat insulating part Su in which the block 3 is embedded apart at a space therefrom, thereby forming a flow passage 17 for a part of the gas in the oven 4. A discharge path P is so formed as to discharge the gas in the oven 4 via a casing C to the outside. If the oven is constituted in the above-mentioned way, the heat generated from the sample evaporating chamber and the detector is discharged to the outside via the discharge path, by which the cooling efficiency is improved.
