| Zusammenfassung: | The invention relates to a method for operating a gas-sampling probe (1), wherein a gas to be analyzed is removed from a process chamber (17) in the region of a front end (1a) of a gas-sampling tube (2) and is conducted in the gas-sampling tube up to a rear end (1b) while being cooled at the same time, in that cooling air (14) is conducted between the gas-sampling tube and at least one outer jacket (3) surrounding the gas-sampling tube, wherein the cooling air is supplied and discharged at the rear end of the gas-sampling tube and the temperature of the gas to be analyzed in the region of the front end of the gas-sampling tube is higher than the temperature of the supplied cooling air, and the gas-sampling tube radiates outwardly, wherein the temperature of the supplied cooling air is higher than the temperature of the discharged cooling air. |
