Abstract
Size fractionated fine particles in Denver, Colorado, were collected by a micro-orifice impactor and analyzed for mass and elemental composition by a beta-gauge and an X-ray fluorescence spectrometer. A least squares procedure was used to fit a log normal distribution function to the data in order to determine values and uncertainties for the mass median diameter and geometric standard deviation. The validity of the uncertainties so determined was tested by comparing them to uncertainties derived from Monte Carlo simulations.
