The system includes at least one sampler including a body having a hollow interior accessed through holes in the body and optionally a slide which can selectively cover and expose the holes in the body. A stand is provided made of a base and a floor. The base includes at least one recess therein. The recess is configured to support the sampler therein so that the sampler can be held by the stand while sampling an airspace at a particular location. The floor can be separated at least partially from the base in a removably attachable fashion to provide selective access to a hollow inside. A sampler can be placed within this hollow inside space and resealed so that the stand doubles as a shipping container for the sampler after collection of an air sample.

Air sampling system

Stand for air samplers

A gas sampler includes an impact disc for removing larger particles from a gas flow drawn by a pump and a filter for capturing smaller particles, also positioned in the flow path. The sampler is conveniently dissembled and reassembled to remove and replace the impact disc and the filter. Particles removed, especially on the filter, may be observed or analyzed. The impact disc may be coated with an oil or other viscous substance to enhance its ability to retain larger particles. The flow path may be entirely annular after striking the impact disc&#x2014;that is, around the outside of the impact disc but a portion of the flow path may proceed directly through a central aperture in the impact disc after striking it.

Modular particulate sampler

An air sampler is designed for a predetermined flow rate. The air flow is admitted to at least two impactors operating in parallel. Preferably the inlet nozzles and the outlet orifices of each impactor are sized to achieve predetermined cut-off sizes of particles; preferably the composite curve of all the impactors will mimic a predetermined particle sampling efficiency curve.
