ABSTRACT:
A condensation nucleus counter has a humidifier zone, through which the sle air is guided, and an approximately perpendicularly arranged condensation zone, as well as an optical detection system with a light source and detector. The humidifying zone has a duct made of a permeable material and a hollow space surrounding this duct, the hollow space being used for receiving the process fluid. The condensation zone has a duct which, in turn, has a hollow space used for receiving the coolant. The condensation zone is connected with the humidifying zone by a connection piece.
