Modification of the Versatile Aerosol Concentration Enrichment System (VACES) for conducting inhalation exposures to semi-volatile vapor phase pollutants

► The sampler is designed to provide concentrated SV purely in vapor phase. ► The health effects attributed to pollutants may be affected by their phase. ► The PM-bound SV species in vapor phase can be used for inhalation exposure studies. ► The performance of the sampler has been characterized in lab and field.
