    Abstract: A leak detection system comprising: an adapter configured to be coupled to a conduit and direct leakage from the conduit to a leakage sensor, wherein the adapter comprises a wick comprising: a hydrophilic material, a cationic polymer material, an anionic polymer material, a hydrophilic non-ionic material, or any combination thereof. A leak detection system comprising: a laminate adapted to transport leaked fluid from a conduit to a leakage sensor, wherein the laminate comprises: a wick adapted to transport the leaked fluid; and an adhesive adapted to secure the wick to the conduit. A leak detection system comprising: a wick disposed on a substrate and adapted to transport leaked fluid from a conduit to a leakage sensor, wherein the wick comprises a plurality of fluid channels in a matrix arrangement.
