Characteristics and Sampling Efficiencies of OMNI 3000 Aerosol Samplers
Abstract
Characteristics and aerosol sampling efficiencies of four Omni 3000 aerosol samplers (Sceptor Industries, Inc., Kansas, MO) were determined at ECBC. These samplers have nontraditional wetted-wall cyclones to collect and concentrate aerosols into liquid. The sampling efficiency tests were conducted with monodisperse 0.5-, 1-, 3-, and 5-mum fluorescent polystyrene latex (PSL) microsperes and 2.9-, 5.8-, and 8-mum fluorescent oleic acid particles. The results showed the highest sampling efficiency of 91% for 3-mum particles using the fluorescent PSL microspheres and 70% for 2.9-mum liquid fluorescent oleic acid particles. Omni aerosol samplers have approximately 277 L/min of air flowrate, use 83 W of power, depending on the attachments, and they are small in size. They give approximately 11 mL of liquid after each sampling. These samplers are portable, battery operated, and easy to use and decontaminate.
