The Dual Membrane PDB™ (DMPDB) is a passive diffusion sampler for groundwater that provides representative, discrete interval samples of nearly any dissolved compound in groundwater without purging or pumping. Use the chart below to select which size Dual Membrane PDB is appropriate for your project.

*If Sampling for PFAS, please use the HDPE diffusion sampler found under: Dual Membrane PDBs for PFAS

SKU: N/A Categories: ,

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.

The DMPDB is constructed from two semi-permeable membranes of different porosity, which allows this wider array of analytes into the sampler as compared to the original PDBs that sampled for VOCs only.

Why Use the Dual Membrane PDB™?

  • Sample for a wide range of analytes (not just VOCs)
  • Reduce sampling cost 50%-80%
  • Eliminate time spent purging and disposal of IDW
  • Highly Portable, No Special Tools or Equipment
  • Obtain Depth-Specific Concentration
  • Can be used for Vertical Profiling
  • Can be used to Sample Slow Recharge Wells
  • A Greener sampling method; less disposable material, no batteries, gasoline or waste.

Custom Suspension Tether Preparation Service

Don't spend time on site measuring out where to put your samplers to collect accurate samples. EON will use your well construction data to construct cut-to-length suspension tethers for individual wells so that all you need to do on each sampling event is connect your samplers to the pre-set attachment points. Click here for more detail.
