Abstract: The invention is a portable sampling system for sampling various media for contaminants. The media sample can include gases, liquids, and dry powders. The contaminant sample can include gaseous components, particulates of various kinds, and microorganisms. The system can be used to sample the surfaces of fruits and vegetables, meat carcasses, the interior of envelopes of other containers, gases in rooms or containers, and surfaces such as countertops, a vehicle exterior, skin, and clothing.

Abstract: The invention is an air sampler which utilizes a hydrophobic filter and an entrapment fluid contained within a sampler body. Air to be sampled is bubbled through the entrapment fluid, which traps and retains a selected air component for later testing. Air which is thus bubbled through the entrapment fluid passes through a hydrophobic filter before leaving the sampler body. A hydrophobic filter prevents aqueous liquids from exiting the sampler body. This allows a higher rate of air flow, because the sampling fluid does not diminish as quickly due to suspended droplets exiting the sampler body. The sampler body may also be inverted to rinse down the walls of the sampler body without losing any liquid, due to the presence of the hydrophobic filter. The entrapment fluid can be poured or drained out of the sampler body.

Abstract: A microbial sampling, filtration, and recovery device which utilizes a wash solution on meat carcasses and a vacuum source to vacuum the wash solution and suspended microbes into a collection device. The collection device includes pre-filters for removing debris, and a microbial filter. The filter is small enough to filter out bacteria, and since this size of filter seriously reduces air flow, an alternate route for air is provided through a hydrophobic filter. Bacteria captured on the filter is back-flushed into a collection vessel where it is concentrated in a subsequent centrifuge step. The concentrated microbial sample is available for use in rapid detection methods.
