摘要： The present invention discloses a thin reagent containing film sensor for detecting and measuring free chlorine in water, where components of the film sensor are a polymeric substrate that contains reactive material, an organic polyhydroxy compound, a reagent that creates an associated polymeric matrix, and an indicator; and a method for making the same. The film sensor can be formed to fit a specific dimension or shape. The film sensor swells or dissolves when exposed to aqueous solutions so that said reagent is released so that it can react with free chlorine, or the film sensor swells when exposed to aqueous solutions so that the aqueous solution diffuses into the film sensor and reacts with said reagent contained within the swollen film sensor.

摘要： Methods are provided for improving the stability and shelf life of film sensors. The film sensors include a combination of polymeric matrix film material, analyte indicator, and solvent which has been heated in a first heat treatment application to volatilize most of the solvent and to solidify the analyte indicator to form the film sensor. The improvement comprises subjecting the film sensor to a second heat treatment to set the film and improve stability and shelf life.
