(57) In a method for analyzing samples of a gas in a rotary cement kiln by means of at least one gas sampling probe, a first and a second gas sampling probe are provided, wherein the first gas sampling probe is moved so as to reach a sampling position, wherein gas samples are withdrawn from the kiln and analyzed by means of the first gas sampling probe being in the sampling position, while the second gas sampling probe is kept in a retracted position and is purged, whereupon the second gas sampling probe is moved so as to reach a sampling position, and the first gas sampling probe is moved from the sampling position to the retracted position and is purged, while gas samples are withdrawn from the kiln and analyzed by means of the second gas sampling probe being in the sampling position.
