  • Method and system for detecting vapors
    Patent number: 7963146
    Abstract: A method and system may include receiving a sample gas from an ambient environment on a first surface of a selective isolation device within an inlet assembly, dispersing the sample gas in substantially a first direction along the first surface, and circulating a carrier gas through a main assembly coupled to the inlet assembly, the main assembly defining a carrier gas environment. The method and system also may include selectively passing analytes from the sample gas through the selective isolation device to a second surface of the selective isolation device, the selective isolation device separating the ambient environment from the carrier gas environment, dispersing the carrier gas in substantially a second direction along the second surface, and obtaining the analytes in the carrier gas from the second surface.
