Abstract An intercomparison study was carried out to evaluate the performance of 11 different designs of aerosol samplers. The samplers were operated by participating scientific groups having recognized expertise in sampler development and operation. The devices tested include hi-vol, TWO MASS, cyclone, CHAMP, streaker, stacked filter and manual and automated dichotomous samplers. The samplers were operated in Charleston WV for eight consecutive days during May of 1977. The collection surfaces of each sampler were changed at least every 12 hours which enabled the intercomparison to be made for 16 sampling periods. The collected samples were returned to the laboratory of each participant and analyzed for mass, nitrate, sulfur or sulfate, lead, and 9 other elements. Most of the samplers separated the aerosol into two fractions with 50% separation diameters ranging from 2.4 micrometers to 4.3 micrometers. The upper 50% cutoff diameter for the various samplers ranged from 14 micrometers to about 30 micrometers. Best agreement among samplers was found for elements such as sulfur and lead that occurred primarily in the fine fraction. The amount of total mass collected was strongly influenced by the upper 50% cutoff diameter of each sampler. For stacked filter samplers and the tandem filter samplers, the fine fraction appeared to be enriched with crustal elements such as Si, Ca, and Fe, which suggests that there are particle bounce errors. Of all the samplers tested, the automatic dichotomous sampler showed the greatest precision.
