Disclosed herein is a variable soil sampling device which may be customized with respect to sampling rate and sorbent material used. Multiple variable sampling devices may be attached to each other to simultaneously sample different components or contaminants in the same time period.

Variable soil sampling device

A passive air sampler is designed to allow for multiple sorbents and multiple sampling rates. The passive air sampler is also reusable and has interchangeable sorbents.

Versatile passive air sampler

Controlled distribution grain container

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

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

A passive air sampler is designed to facilitate emptying granular or particulate adsorbent from it directly into a thermal desorption tube or other vessel for use in an analytical instrument. The preferred form has an adsorbent container in a conical or funnel-like shape.
