Table 1. Compounds tested under laboratory conditions for use with passive diffusion bag samplers. 7 Simple (passive) diffusion The unique design of biological membranes provides a barrier separating a hospitable environment inside the membrane from the external environment. Regardless of cell function, membranes give every cell and organelle a spatial definition and keep separate contents on either side of the membrane, often at a considerable gradient. High quality gas sampling bag with the classic Polypropylene combo valve with septa. Made using DuPont Tedlar® Film. The valve is located at the top of the bag making the auto sampler loading easier.

Hung in monitoring wells for periods of 14 days, or until equilibrium is complete between the contaminants in the bag and surrounding groundwater, the PDB operates The general principles behind Passive Diffusion Bag (PDB) sampling and groundwater sampling using the HydraSleeve (HS) are very similar. Both devices collect a discrete sample from within the screened interval of the monitoring well without purging, and rely on ambient flow and diffusion of contaminants from the aquifer into the well screen. 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.
