Abstract

The present invention relates to an apparatus (1) for monitoring particles (54) in a channel (11) or a space comprising aerosol. The apparatus (1) comprises an inlet chamber (4), an ejector (24), gas supply (6, 16, 18) arranged to feed essentially particle free gas flow (C) to the ejector (24) via the inlet chamber (4) and at least one sample inlet (2) arranged to provide a sample aerosol flow (A) from the channel (11) or the space into the inlet chamber (4) by means of suction provided by the gas supply (6, 16, 8) and the ejector (24). The apparatus (1) further comprises a sample supply channel (5) arranged between the sample inlet (2) and the inlet chamber (4) for mixing the 1 sample aerosol to the essentially particle free gas flow (C). The sample supply channel (5) is arranged to direct the sample aerosol flow (A) at least partly in opposite direction to the essentially particle free gas flow (C).
