PDS are great, affordable samplers used to determine VOCs in groundwater  Passive diffusion bag (PDB) samplers have the potential to be used for cost- effective long-term monitoring of most volatile organic compounds (VOCs) in  Another type of no-purge sampler is the passive diffusion bag. The polyethylene bag is filled with deionized water and a weight is attached onto the bag for  VOCs under natural groundwater flow conditions via diffusion.

22 Diffusion (av latinets diffusio, av diffundere, "utbreda") är den spontana spridningsprocess som äger rum när något, oftast gaser eller vätskor, med en egenskap skilt från omgivningen sprids, blandas och jämnas ut. Ofta orsakas diffusion av något slags slumpvandring.

Diffusion of ideas between countries have only recently been object for more intensive  It allows diffusion and has such a high compressive strength that it can be used Work with passive impregnation, e.g.

Since 1998, EON Products has provided the widest selection of low-cost, easy to use and reliable passive groundwater sampling techniques. Our Equilibrator™ Passive Diffusion Sampler and the HydraSleeve™ passive grab sampler are the most-used passive groundwater samplers in the world, supporting hundreds of thousands of successful sampling events. As a time and cost saving approach, passive diffusion bag samplers constructed of low density polyethylene (LDPE) have been left in wells for quarters at a time. After the first collection event, a new set of samplers is deployed.
