Generally, a PDB sampler consists of a semi-permeable membrane tube made from low density polyethylene (LDPE) that is filled with laboratory grade deionized water and placed at a specific location within the screened interval of a 6.9.2.5.1 Passive Diffusion Bag Samplers (PDBS) 6.9.2.5.1.1 Introduction 6.9.2.5.1.2 Limitations And Concerns 6.9.2.5.1.3 Theory 6.9.2.5.1.4 PDBS Construction 6.9.2.5.1.5 Contaminant Detection Capabilities Table 6-13 Passive Diffusion Bag Samplers (PDBS) 6.9.2.5.1.6 Well Construction Considerations Passive Diffusion Bag (PDB) samplers consist of a low-density polyethylene sleeve, filled with laboratory-grade deionized water, and closed at both ends. Pictured here are three types of diffusion samplers commonly used and commercially available. The samplers on the left are supplied prefilled with laboratory-grade deionized Passive Diffusion Bag Samplers for Monitoring Chlorinated Solvents in Ground Water: The Second International Conference on Remediation of Chlorinated and Recalcitrant Compounds, Battelle, May 22–25, 2000, Monterey, California, v.2, no 1, p. 377–386. Google Scholar Key limitations include: 1) some passive samplers cannot be used for all analytes, 2) some passive samplers may not be able to collect sufficient sample volume for all required analyses, 3) some passive samplers may not fit into wells smaller than the common 2-inch diameter well, 4) some devices are not appropriate for “total” or unfiltered sample analysis because of diffusive filtration, and 5) some methods (i.e., sorptive methods) produce a calculated concentration rather than a Passive diffusion samplers have been tested at a number of sites where volatile organic compounds (VOC's) are the principal contaminants in ground water.

The samples were then put in vacuum bags to eliminate the risk of any  ALS Passive Diffusion Bag samplers (PDBs) are used to collect water samples from groundwater aquifers for analysis of specific chemical compounds. Passive diffusion samplers are used to collect water samples from groundwater aquifers for analysis of specific chemical compounds. The samplers are hung from a cable and placed in monitoring wells at the well screen for periods of at least 14 days, or until equilibrium has taken place between the water in the sampler and surrounding groundwater. authorized distributors from whom passive diffusion bags can be obtained.
