GAS CHROMATOGRAPH DEVICE

PROBLEM TO BE SOLVED: To cool quickly a column and an oven, even when an intake port for taking the outside air into the oven is arranged close to an exhaust fan for circulating the air in a space between the oven and a casing. SOLUTION: An exhaust port 24 and the intake port 26 for discharging/sucking the air from/into the oven are provided in parallel vertically on a right half of a rear surface part of the casing 12. The exhaust fan 30 for cooling a peripheral wall of the oven by circulating the air in the space between the casing 12 and the oven is provided on the left of the intake port 26 on the rear surface part of the casing 12. An L-shaped partition plate 37 is provided between the exhaust fan 30 and the intake port 26, and between the intake port 26 and the exhaust port 24, to thereby prevent high-temperature air discharged from the exhaust fan 30 and the exhaust port 26 from flowing into the oven from the intake port 26.
