An adapter for use with a low volume PUF sampler is described. The adapter is affixed over the open end of a PUF (polyurethane foam) sample cartridge. Sample tubing is affixed to an aperture in the adapter, and the free end of the sample tubing is then positioned at a desired sample location such as within an aircraft interior. As a vacuum is applied to the PUF cartridge, the adapter allows air collected at the sample point to pass through the tubing and through the interior of the PUF cartridge while preventing air surrounding the PUF cartridge from being drawn into the PUF cartridge except through the sample tubing. In this manner the sample point of a desired air sample can be selected at a point remote from the PUF cartridge. Additionally, use of multiple PUF cartridges and adapters allows the simultaneous collection of separate air samples.
