| description | Devices and methods for extraction, identification, authentication, and quantification of one or more covert markers in a material are disclosed. An extraction system includes a first plug flow mixer for mixing a first fluid bearing a marker and transfer agent into a plug flow. The mixing and flowing of the immiscible liquids causes transfer of the marker from the fluid to the transfer agent. A splitter having filters of different surface energies separates the two immiscible liquids, the transfer agent bearing the marker. A second plug flow can be used to transfer the marker to a second transfer agent. The transferred marker is detected to authenticate the original fluid. The marker can be further isolated, activated, or reacted to perform detection, identification or authentication. With the device, a number of independent processing and analytic steps are combined onto a single, portable unit. |
