Abstract

An additive is introduced into a fluid system and dissolved in a carrier fluid which is immiscible or slightly miscible in the fluid system, wherein the carrier fluid is subsequently removed from the fluid system. This method can be used to detect leaks, wherein an on-off UV light source, such as xenon light, can be used to detect the leak visually.
