ORSA Organic Vapor Sampling Badges
The ORSA Organic Vapor Sampling Badges are a diffusion sampler for monitoring organic compounds. The contaminant molecules from the ambient air are adsorbed by the activated charcoal which is later analyzer using laboratory methods.
ORSA is used to determine average concentrations from 1 to 8 hours and for the investigation of lower concentration ranges over prolonged periods of time (e.g. 168 hours for the sampling of perchloroethylene). The ORSA includes 5 samplers, holders and shipping vials.
