ORSA Passive Sorbent Samping Badges from Draeger Safety

The ORSA is 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. The ORSA 25 includes 25 samplers, 10 holders and 25 shipping vials.
