(57) Summary of the corresponding patent EP3608667 (A1): In a method for analyzing samples of a gas in a rotary cement kiln by means of two gas sampling probes (1,2), wherein the first gas sampling probe (1) is moved so as to reach a sampling position. Gas samples are withdrawn from the kiln and analyzed by means of the first gas sampling probe (1) in the sampling position, while the second gas sampling probe (2) is kept in a retracted position and is purged. Then the second gas sampling probe (2) is moved so as to reach a sampling position, and the first gas sampling probe (1) is moved from the sampling position to the retracted position and is purged, while gas samples are withdrawn from the kiln and analyzed by means of the second gas sampling probe (2) in the sampling position.
