Abstract
According to an example aspect of the present invention, there is provided an apparatus comprising a volume for receiving a gas sample; and an ultrasonic transducer; wherein the ultrasonic transducer is caused to generate a standing wave to the volume, said standing wave comprising at least one particle trapping zone for trapping particles carried by the gas sample, and to release particles trapped to the at least particle trapping zone by decreasing power of the standing wave to at least one lower power level and/or switching off the standing wave.
