An apparatus for collecting particles from internal combustion engine exhaust gases is disclosed. The apparatus comprises at least one unobstructed flow channel (1) and preferably a plurality of parallel unobstructed flow channels with a diameter of around 3-30 mm and a length of around 10-100 cm. The or each channel is surrounded on all sides by spaces, cavities or pockets (2) around 1 mm wide and around 5 mm deep in a direction perpendicular to the axial direction of the channel, said channels being such that the exhaust gases flow at around 5-50 m/s.
