The funnel-shaped inlet of the British Smoke Shade Sampler was tested in a wind tunnel to characterize aerosol penetration as a function of particle size and wind speed. Cutpoint sizes of 13.S and 10.8?m were noted at wind speeds of 2 and 8 km h?1, respectively. Tests of aerosol penetration through the complete sampling system, including the inlet, connecting tubing, manifold and filter holder, showed the cutpoint to be 4.4 ?m. Tubing losses appear to control the transport of the larger particles.
