Particle Size Metrology: Comparison Between Aerosol Electrical Mobility and Laser Surface Light Scattering Techniques

Abstract
Two different methods used to determine the size of polystyrene spheres were found to disagree by about 5 %. One of the methods, differential mobility analysis, measures particles in the aerosol phase, while the other, laser surface light scattering, measures them bound to a surface. It is believed that the observed discrepancy results from deformation of the particle when it bound the surface. The implications of such a deformation on scanning surface inspection system calibration is discussed.Proceedings Title
