Abstract
Particulate reference samples have been prepared for the standardization of x-ray fluorescence spectrometers used in the analysis of air particulate matter for air pollution detection methods. Uniform layers of reground orchard leaves of known composition, i.e., National Bureau of Standards Standard Reference Material SRM 1571, were deposited on membrane filters and coated with a thin polymer film for protection against abrasion and moisture. These samples have been prepared with areal densities of 0.1 to 5.0 mg/sq. cm.
