Abstract: Disclosed herein are systems and methods for measuring one or more target analyte concentrations, particularly peroxyacid compounds, in a process solution, for example, in industrial and commercial water. These systems and methods include automated methods to measure the target analyte concentration in the process solution. The methods have the advantage of providing a large dynamic range for measurement and can be used in a wider range of process solutions.

Abstract: A heated development/transport roller having improved film release properties is provided by applying a fluorocarbon coating on the outer surface of the roller. The fluorocarbon coating may be applied onto the resilient layer surface of the roller by simply wiping a solution of the fluorocarbon material onto the resilient layer surface. There is no need for special coating conditions nor any post thermal curing or fusing conditions. The solvent is removed by application of heat either from the heating means of the roller or from an external heating source. The fluorocarbon coating provides improved film release and transport characteristics especially when applied to a hot silicone coated aluminum roller.
