A method for operating a gas sampling probe includes removing a gas to be analyzed from a process space in the region of a front end of a gas sampling tube and conducting it through the gas sampling tube as far as a rear end and, in the process, cooling it by passing cooling air between the gas sampling tube and at least one outer casing enclosing the gas sampling tube. The cooling air is fed and discharged at the rear end of the gas sampling tube and the temperature of the gas to be analyzed is higher in the region of the front end of the gas sampling tube than the temperature of the fed cooling air, and the gas sampling probe emits outward, wherein the temperature of the fed cooling air is higher than the temperature of the discharged cooling air.
