Abstract:
1. A method for microbiological testing of gases comprising the steps of: contacting a liquid bacteria growth medium for microorganisms of interest disposed within a lower region of a portable sampling vessel with a gas sample of interest, said lower region separated from an upper region within said sampling vessel by a hydrophobic filter element and having a headspace above said liquid bacteria growth medium sized to provide a headspace to liquid ratio of one of greater than and equal to about 1:1; passing said gas sample of interest through said hydrophobic filter element whereby said microorganisms in said gas sample of interest are retained on said hydrophobic filter element; inverting said sampling vessel, thereby submerging said hydrophobic filter element in said liquid bacteria growth medium; incubating said sampling vessel for a predetermined period of time at a predetermined temperature; and determining a presence of said microorganisms based on at least one of turbidity and color of said liquid bacteria growth medium.
