Abstract
Many substances can exist in an atmosphere as both particles and vapor. However, current sampling methods, such as National Institute of Occupational Health and Safety (NIOSH) methods, still recommend filtering methods for some contaminants that exist in both phases. A problem during sampling with filter media is that the volatile or semi-volatile particles retained on filters evaporate during sampling into the air passing through the filter. This evaporation leads to inaccurate measurements of aerosol concentration. The objective for this study was to develop a new personal sampler that can separate vapor-phase contaminants and particle-phase contaminants based on the greater inertia that particles possess. The new prototype vapor/aerosol samplers have been developed and characterized for cutsizes. These samplers would be relatively simple and inexpensive personal and field sampling devices.
