Abstract : Characteristics and aerosol sampling efficiencies of two units of the same model Personal Aerosol Sampler (PAS-1 and PAS-2) were characterized at ECBC. These samplers were designed and manufactured by Research Center for Toxicology and Hygienic Regulation of Biopreparations at the Federal Directorate of Medical, Biological and Extreme Problems Medbioextrem, Ministry of Health of the Russian Federation, Russia. These samplers have non-traditional wetted wall cyclones to collect and concentrate aerosols into liquid. The samplers are small, portable, and easy to use for decontamination. The sampling efficiency tests were conducted with monodisperse 0.5-, 1-, and 2.1-micrometre fluorescent Polystyrene Latex (PSL) microspheres, and 5.8- and 9.6-micrometre fluorescent oleic acid particles. The air flow rate of PAS-1 was 10 Lpm and the air flow rate of PAS-2 was 9 Lpm. The sample output volumes for PAS-1 and PAS-2 were 1.9 + or - 0.5 cu cm and 2.0 + or - 0.5 cu cm, respectively. The results of PAS-1 and PAS-2 showed the highest sampling efficiency of 72.6% + or - 6.8 and 77.6% for 5.8-micrometre particles, respectively. The power requirements of these samplers will depend on the vacuum pumps used to pull the air through the samplers.
