Abstract

The present invention relates to a device (10) and a method for detecting particles in a flow The device (10) comprises a particle chamber (11) having an inlet (12) and an outlet (13) for a flow containing particles flowing through the particle chamber (11), and a detector (15) for detecting particles in the flow containing particles, the detector being arranged at an angle towards the particle chamber (11). The detector (15) is arranged in a detector chamber (14) being arranged at an angle to the particle chamber (11), the detector chamber (14) being connected to the particle chamber through an aperture (20) through which detection can be performed, and the detector chamber (14) being provided with an intake channel (21) for introducing a counterflow, wherein said counterflow can flow in through the intake channel (21), through the detector chamber (14) and out through the aperture (20) at an angle to the flow containing particles to prevent this from entering the detector chamber (14).
