In recent years, filtration has been the most widely used technique for collection of atmospheric particulate material, primarily because of its low cost and simplicity. This not measurements of the electric charge in a Nucleopore filter attained with a simple device able to detect induced charge in a metallic plate which is registered through a 610B KEITHLEY electrometer. A mathematical model to describe the temporal behavior of this charge is also presented. The filter used was a polycarbonate membrane with 47 mm in diameter, 10 {mu}m thickness and 0.4 {mu}m pore diameter. The sampling system was a Stacked Filter Unit{sup 2} with a flow about 8 L/min. Both filter and filter holder are provided by Nuclepore Corporation.
