Abstract
A chemical pre-concentrator includes a conduit defining a flow path between two ends and having a heating element disposed within the conduit, such that the heating element has at least one sorbent material deposited directly on at least a portion of a conductive surface of the heating element. Some such heating elements are in the form of electrically conductive strips defining both a plurality of apertures through the strip and a series of undulations spaced along the flow path.
