Abstract: The present invention provides a kit and a method of testing for carbamates in amine cured epoxies. The method and kit are based on the use of an enzyme that is inhibited by carbamates. A specific embodiment of the kit includes acetylthiocholine (ATC), dithio-bis (2-nitrobenzoic acid) (DTNB), and acetyl-cholinesterase (ACh-E). In the corresponding method embodiment, the method comprises the steps of collecting carbamates from the epoxy, adding the collected carbamates to a solution, adding acetyl-cholinesterase (ACh-E) to the solution, adding acetylthiocholine (ATC) to the solution, adding dithio-bis (2-nitrobenzoic acid) (DTNB) to the solution, and ultimately measuring the intensity of the yellow color of the solution.
