In one example, a sample gas analyzer includes a sample cell configured to receive a gas sample, a sample tube including a passageway that is in communication with the sample cell, and an intake portion. A cleaning element is disposed between, and arranged for fluid communication with, the sample tube and the sample cell, and includes a body having a chamber configured to aid in imparting a rotational motion to a fluid stream entering the chamber. The cleaning element also includes an inlet port that is in communication with the chamber and that is configured and arranged for communication with the atmosphere. Finally, the cleaning element includes an outlet port in communication with the chamber and the sample cell.
