Abstract
A device (201) is provided for collecting signatures from an ambient fluid. The device includes a housing (205) equipped with an (207) inlet and an outlet (209) which are in fluidic communication with each other, and a signature collector (203) which has a plurality of spaced-apart layers (213). The signature collector is disposed in a fluidic flow path between the inlet and the outlet such that a flow of fluid passes through adjacent layers of the signature collector. Each of the layers includes a substrate (217) having a sorbent or adherent (219) disposed thereon, and a plurality of embossments (215) which maintains the layers in the spaced-apart configuration.
Claims22
A device, comprising:
- a housing equipped with an inlet and an outlet which are in fluidic communication with each other;
- a wound substrate having a plurality of discrete embossings that maintain adjacent layers of the substrate in a spaced-apart relation to each other, wherein said substrate is disposed in a fluidic flow path between said inlet and said outlet such that the flow path extends through the spaces between adjacent layers in said substrate;
- and
- an adherent disposed on said substrate such that the adherent is in fluidic contact with said flow path.
2-19. (canceled)
A method for collecting a signature from an ambient fluid, comprising:
- providing a device comprising (a) a housing equipped with an inlet and an outlet which are in fluidic communication with each other, and (b) a signature collector which has a plurality of spaced-apart layers and which is disposed in a fluidic flow path between said inlet and said outlet such that a flow of fluid passes through adjacent layers of the signature collector, wherein each of the spaced-apart layers includes a substrate having discrete embossments and further having an adherent disposed thereon;
- and
- passing the ambient fluid through the device such that the signature is captured by the signature collector.
24-25. (canceled)
The method of claim 25, wherein said discrete embossments include a plurality of hemispherical protrusions.
