Passive Diffusion Sampling

Passive diffusion samplers are used for the collection of groundwater when the analysis of volatile organics is required. The samplers are hung from a cable and placed down into monitoring wells for periods of about 14 days or until equilibrium is considered to have taken place between the contaminants in the sampler and the surrounding groundwater. It operates by diffusion of contaminants across the polyethylene membrane. No purging or disposal of purge water is necessary, which significantly reduces your costs in sampling.
