摘要: Transmission measurements have been performed on University Research Glassware, Inc. model 2000–30B glass annular denuders at 10 L/min using monodisperse particles in the 0.01–1-μm diameter size range. Through control of aerosol charge state, particle losses due to diffusion and electrostatic effects were separately measured theoretical descriptions both developed. For Boltzmann charged (atmospheric) important 0.1–1-μm range total averaged only a few percent or less. Particle transmission also confirmed design value 2.5 μm for 50% cutpoint URG 2000-30EN cyclone inlet used with these denuders.
