Abstract:
An air sampler for use with an air pump for sampling air, comprising:a sampler body for collecting selected air components with a mid and a base section; an air intake for admitting air and air components from a sampling environment into said sampler body, driven by said air pump; an entrapment fluid contained in said sampler body, for entrapment of said selected air components; an impinger tube for impinging air into said entrapment fluid; an air outlet, which provides a route for air to exit said sampler body, driven by said air pump; a hydrophobic filter, positioned to prevent loss of entrapment fluid from said air sampler, for preventing liquid and entrained contaminants from exiting said sampler body through said air outlet, in which the hydrophobic filter is a polytetrafluoroethylene; a particulate filter for capturing air components and separating said air components from said entrapment fluid for testing and quantitation; and a filter support for said particulate filter for said particulate filter between said mid section and said base section.
