Abstract
A passive diffusion sampler and kit that includes a passive diffusion sample bag comprising a regenerated cellulose membrane to allow for sampling of a broad spectrum of contaminants and VOCs. The sample bag is disposed in a rigid housing which protects the bag from tearing and also allows the housing to be inverted to suspend the bag upside down and provide a user access to a fluid outlet means on the bag for withdrawing a sample from the bag without agitating the sample.

- a rigid housing configured for accepting the sample bag, and
- retaining means for releasably holding the sample bag to a top end and bottom end of the housing but out of contact with the housing, thereby allowing the sample bag to be inverted.
