Abstract: 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.

Abstract: 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.

Abstract: 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—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.

Abstract: 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.

Abstract: The present invention relates to a housing system adapted to connect single or twin coaxial cable to a printed circuit board. More particularly the invention provides one housing having contact pins therein which is attached to the board by soldering or insertion into spring socket members. The invention further provides a second housing latchable to the first and adapted to carry terminals which plug into the contacts.
