title: Performance of adhesives for rotating-arm impactors.
abstract: Particle collections by paired rotoslide surfaces coated differentially with either of two silicone greases, white petrolatum or Lubriseal, were compared in two series of studies. Three samplers were employed, and adhesives were assigned randomly to the six available positions. Recovery differences were small but occasionally significant, with counts generally highest for silicone grease and lower with Lubriseal. During natural and simulated rainfall relative performances were similar, although differences were accentuated.
