发明名称 Vacuum air component sampler
摘要 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.
