Abstract
A method, device, and article of manufacture for detecting airborne sulfur, the method including obtaining a gel solution; applying the gel solution onto film; exposing a frame of the film on the film reel to surrounding air, where the surrounding air contains a concentration of airborne sulfur; and detecting a color change in the gel solution, where the color change is a response to a reaction between the amount of airborne sulfur and at least one component of the gel solution. The device may include a detector; a film; and a gel solution applied to a film. The article of manufacture may include a film; and a gel solution applied to a film.
