Groundwater Pumping and Sampling

EON Products Equilibrator Diffusion Sampler

Practical and easy to use!

A semi-permeable sample chamber is filled with inexpensive deionized or distilled water, then lowered into the well screen and left in place. VOCs on the groundwater diffuse into the sampler until the concentration gradient equilibrates between the water in the formation and the sampler. The sampler is retrieved and contents easily emptied into VOA vials for laboratory analysis.

Save Sampling Time!
Install samplers during one round of sampling and retrieve them during the next round.

Reliable and Inexpensive!
Results correlate with bailing and low-flow sampling without expensive equipment and labor intensive purging.

EON Equilibrator™ Diffusion Samplers are currently in use at U.S. DoD sites, EPA-monitored sites, major industrial sites, and small petroleum monitoring sites across the U.S. Diffusion sampling technology is licensed by the U.S. Government.
