Methods, compositions, systems and devices are provided in which zeolite particles, preferably of silicon and aluminum, are used as desiccants. In embodiments a plurality of zeolite particles are provided that are less than 1 mm in size. The particles may be arrayed such that at least some of the plurality of particles are spaced apart from each other and may be arrayed in rows and columns. Embodiments provide the particles are useful or removing water under ambient conditions and in removing water from air or material and in an embodiment removing water from plant material, such as harvested crop material, or where the dried air is contacted with plant material. Microwave radiation may be used to efficiently and in a cost effective manner dehydrate the rehydrated particles.

Zeolite particles, systems for using same and methods of use in desiccation

A portable sampling device includes a sampling housing at least partially enclosing an inner chamber; at least one pumping element disposed within the inner chamber and configured to facilitate airflow through the device; and at least one gas sensor disposed within the inner chamber and configured to detect and/or characterize one or more gases in the airflow.

Sampling device for exposure measurement of particles and gases

A portable sampling device includes a housing at least partially enclosing an inner chamber and an airflow assembly disposed within the inner chamber and comprising a portion of an airflow path. The airflow assembly includes a portion of a printed circuit board (PCB); a manifold configured to be sealably coupled to the portion of the PCB to define at least one airflow channel disposed between an inner surface of the manifold and an outer surface of the PCB; and one or more pumping elements positioned on the PCB.

Portable air sampling device

A sampling device is constructed having an airflow path from a size-selective inlet to a device outlet, without using any tubing. The size-selective inlet includes at least one of an impactor, a filter, a cyclone, and an inhalable inlet. The device includes a sampling assembly configured to be removably coupled directly to a sampling device housing (e.g., without using tubing), and an airflow assembly that may be constructed without using tubing.
