Abstract The paper discusses procedures used to obtain mass data on particulates from more than 25,000 membrane filters in an air quality study of 40 remote areas of the United States. Results show that a large number of particulate samples can be analyzed for mass by weighing, with excellent precision and accuracy without a significant increase in sample handling time. Use of an electrobalance has the added advantage of being relatively inexpensive, with values independent of filter orientation, laboratory atmospheric conditions, and the elemental makeup of the particles and the filter substrates. Careful control of electrostatic effects must be maintained, however, and strict adherence to formal quality assurance protocols is essential.
