Abstract
A leak detector having a multi-stage concentrator, consisting of an array of heater elements which desorb analytes in a phased manner, in synch with the sample stream, to maximize sensitivity. The heater elements of the concentrator are coated with adsorber material on both sides of the heater elements, i.e., top and bottom sides, and have small anchor points to minimize power dissipation. The concentrated gas mixture output of the concentrator is electronically injected into a separator, which for separates the constituents of the detected analyte-fluid and recognizing the nature or source of the analyte.
