    DMPDBs are passive diffusion samplers for groundwater that provide representative discrete interval samples of nearly any dissolved compound in groundwater without purging or pumping.



    Why Use the DMPDB™?

    • Sample for a wide range of analytes (not just VOCs).
    • Reduce sampling cost 50%-70% by eliminating field time spent purging and sampling
    • Eliminate the cost of purge-water and investigation derived waste (IDW) disposal.
    • Easy and quick installation and recovery helps in high-traffic areas and for Social Distancing
    • No expensive, complicated, or bulky equipment to purchase, maintain, or mobilize.
    • Obtain depth-specific concentration profiles.
    • Reduce sampling error and improve repeatability.
    • A Greener sampling method. Less disposable material, no batteries, gasoline or waste


    EON’s Dual Membrane™ Passive Diffusion Sampler (DMPDB™) is the world’s number one PDB for sampling virtually any analyte, including; VOCs, SVOCs, Metals, Ions, Cations, Inorganics, and the compounds of emerging concern, 1, 4 Dioxane and PFAS.
