Passive Sampling Technology
Powerful sampling tool for various screening or monitoring studies and media
The application of passive sampling technologies for monitoring of chemicals in the environment is becoming widely accepted worldwide. Passive samplers represent an innovative tool for monitoring of a wide range of environmental pollutants in water and in the air. The use of passive samplers greatly reduces the cost and the need of infrastructure on the sampling location. Three of the most commonly used passive samplers of organic contaminants in aqueous environment are the Semipermeable Membrane Device (SPMD), and Silicone Rubbers for nonpolar hydrophobic contaminants and the Polar Organic Chemical Integrative Sampler (POCIS) for polar contaminants readily dissolve in water. Metals can be measured by the Diffusive Gradient Thin Films (DGT) technology.
The Passive air sampler (PAS) with the polyurethane foam (PUF) sorbent is suitable for monitoring of selected persistent organic pollutants (POPs) in the air.
