Particle Morphology and Density Characterization by Combined Mobility and Aerodynamic Diameter Measurements. Part 1: Theory (2004, background): “In these devices, a series of axisymmetric lenses collimate aerosol particles into a tightly focused beam (Liu et al. 1995a, b; Zhang et al. 2002, 2004b).”
Transmission Efficiency of an Aerodynamic Focusing Lens System: Comparison of Model Calculations and Laboratory Measurements for the Aerodyne Aerosol Mass Spectrometer (2007, methodology): “In our previous studies (Zhang et al. 2002, 2004), we have taken into account the effects of Brownian motion in the flight chamber on the transmission efficiency, but have not considered Brownian motion within the aerodynamic lens.”
Design, Modeling, Optimization, and Experimental Tests of a Particle Beam Width Probe for the Aerodyne Aerosol Mass Spectrometer (2005, methodology): “Accounting for the effect of size is necessary for a precise definition, since aerodynamic lenses are known to focus different particle sizes differently ( Zhang et al. 2002, 2004c ).”
Characterization of an Aerodyne Aerosol Mass Spectrometer (AMS): Intercomparison with Other Aerosol Instruments (2005, background): “A narrow particle beam is generated by an aerodynamic lens that consists of a series of apertures embedded in a 1/2-inch outer diameter (1 cm inner diameter) stainless steel tube (Liu et al. 1995; Zhang et al. 2002, 2004).”
