<p>A detection apparatus for detecting a substance in an air flow, includes an air supply conduit, a spray generator, a separation chamber, and a first pump. An outlet of the air supply conduit is in fluid communication with an inlet of the separation chamber along an air flow path. A first outlet for fluid of the separation chamber is connected to a sensor. The first pump is arranged for creating an air flow in the air flow path from the air supply conduit to the separation chamber. The spray generator is arranged for introducing a spray of a detection fluid containing detection agent particles into the air flow path. The separation chamber is arranged for separating the spray of detection agent particles from the air flow path into a separated fluid containing detection agent, and the sensor is arranged for receiving the separated fluid containing detection agent and for measuring the state of the detection agent.</p> |
