Patent ID: 7951609

Claim:
A method for operating a purge and trap concentrator system, said method comprising: (a) providing a system controller, a gas source that supplies a first gas flow, a plurality of fluidic control devices and a plurality of fluidic passages which fluidically connect said plurality of fluidic control devices, an analytic trap, a first fluidic inlet that is in communication with an external analyzer instrument, and a first fluidic outlet that is in communication with said external analyzer instrument; (b) receiving a second gas flow from said external analyzer instrument, through said first fluidic inlet; (c) placing a concentrated chemical sample into a first chamber of said analytic trap, directing said second gas flow into a first end of said first chamber and removing at least one predetermined substance from said concentrated chemical sample, thereby creating an extracted sample gas flow that is directed to a second end of said first chamber; and (d) receiving, at a second chamber of said analytic trap, said extracted sample gas flow from said first chamber; receiving, at a second inlet of said second chamber of said analytic trap, said first gas flow from said gas source; and combining said first gas flow and said extracted sample gas flow at said second chamber and to create an enhanced gas flow that is directed through a second outlet of said second chamber and further to said first fluidic outlet, and to said external analyzer instrument, thereby providing a larger overall enhanced gas flow that now becomes available for analysis by said external analyzer instrument.
